As announced in the comments a few days ago in this post is compared to the thermodynamic cycle of the engine Hummingbird with the Rankine cycle through the cycle for engine Uniflow. The three cycles were constructed recovering the same operating conditions adopted in previous posts. It is noted that the diagrams shown below by using exactly the same amount of steam per cycle (0,03492g). The absorption heat in the three cases is therefore identical and equal to 82,4J. The picture below shows the cycle of motor Hummingbird. For details on the cycle, see the dedicated post.
The engine Uniflow adopts the same solution of the Hummingbird as regards the discharge of the steam, zach anner while it is provided with a pilot operated valve as regards the placing of the steam. The piloting of the valve makes it possible both the extraction of work isobar, both the annulment of the pressure difference existing zach anner between the expansion chamber and placing at the time of the opening of the light load thus eliminating the problem of the volume thief. Below is plotted the cycle of an engine Uniflow.
The pressure curve, which in Hummingbird from point C to stop at the point D, nell'Uniflow continues to the point E. In this point the pressure in the engine is equal to the inlet pressure. In point E opens the inlet valve and begins the process isobaric to the point A. At this point, the inlet valve closes and begins the adiabatic expansion up to point B. At point B opens the exhaust port and the pressure returns to step C isochoric process. The diagram shows that, compared to the area of the Hummingbird, the area of the loop dell'Uniflow, that his useful work, increases the area of green (1,5J). The next image is relative to the Rankine cycle, which from the theoretical point of view represents the maximum attainable with the steam.
In the Rankine cycle in addition to the inlet valve, is appropriately piloted also the exhaust valve. zach anner While in the cycle Uniflow (and that of the Hummingbird) the adiabatic expansion is truncated at point B, the Rankine cycle expansion continues to point F. At this point the pressure equals the pressure in the engine exhaust. At this point the exhaust valve opens and starts an isobaric process zach anner to the point C. At point C the exhaust port closes and starts the adiabatic compression and the rest of the cycle continues zach anner in the same way as already seen for the case Uniflow. The diagram shows that, compared to the area of the Hummingbird, the area of the Rankine cycle, ie its useful work, increases the surface of green color (1,5J) and the surface of red color (1,3J). In the following table were collected data relating to the three cycles just discussed. Working useful heat absorbed Performance Cycle Hummingbird 10,8J 82.4 J Cycle Uniflow 13.1% (10.8 + 1.5) J 82.4 J 14.9% Rankine Cycle (10.8 + 1.5 + 1 3) J J 82.4 16.5% The numbers in the table show that the cycle of Hummingbirds can rip Rankine yield of 79.4%, a value surprisingly high in view of the extreme simplicity of the engine. The engine Uniflow, zach anner which is thermodynamically place at an intermediate level between the Hummingbird and the Rankine, produces a yield of 14.9%, which is equivalent to an efficiency of 13.7% compared to the Hummingbird.

The adiabatic ldoc duke transformation The adiabatic expansion of the vapor in the Mollier diagram The isobaric transformation The vapor pressure of water The isothermal transformation The transformation isochoric ldoc duke enthalpy and internal energy density of the water The engine Manson free piston double-acting Vapor Density ldoc duke water: considerations lateral
As the name indicates, the energy of the steam engine in the case of a "flow" or "one-way" is extracted without forcing the return of steam in its path, that is to say that the vapor always moves in one direction through the cylinder. As shown in fig.1, the steam supply enters ldoc duke from below in the hollow cover, heats the surfaces of the lid and then from the valve located in the upper part of the cover passes into the cylinder; the vapor follows the piston cedendogli its energy ldoc duke and after it has been expanded, comes out at the end of the stroke of the piston, through the discharge ports arranged at the center of the cylinder and controlled by the piston. In contrast, in steam engines ordinary steam has an action against the current, that is to say that enters into the cylinder head, follows the piston during its working stroke, and then returns with the piston in its return stroke to discharge through valves that open in the vicinity of the cylinder ldoc duke head. The counter flow or reversal of the exhaust steam causes a considerable cooling of the surfaces of the washing ldoc duke due to their contact with the exhaust ldoc duke steam wet. This cooling action involves a considerable initial condensation when the steam of the boiler steam is again entered to the cylinder ldoc duke for the next working stroke. In a motor-flow, all the cooling surfaces are almost completely avoided, and then the condensations in the cylinder are largely eliminated as is the need to employ different stages of expansion. The motors a flow can therefore be realized with a single phase of expansion, ldoc duke while the steam consumption does not exceed that of steam engines compounds and that of steam engines triple expansion.
Eliminating all the cooling of the surfaces lapped by the discharge of the steam is obtained an effect similar to that obtained with overheating. In ordinary engines, overheating is employed to overcome the above mentioned difficulties caused by the cooling of the surfaces of washing. Now, if this seems redundant cooling is avoided the need for steam heating. The use of a ring of lights or discharge slits in the cylinder ldoc duke allows to obtain a zone of discharge passage three times larger than that obtained by the use of the cassette or other types of valves. ldoc duke The result of this large discharge section is that the final pressure in the cylinder is that of the capacitor, in particular when it is avoided the use of long and narrow connecting pipes between the condenser and the cylinder. In other words, if the capacitor is arranged close to the cylinder and the discharge passage has a large cross section, it is possible to bring the pressure of the cylinder up to that of the capacitor. In order to form a correct idea of the size of the exhaust ports, one should imagine a piston valve of the same size of the working piston and a valve body of the same size of the working cylinder and the piston is moved by an eccentric having the same excursion of the engine crank. On average, the discharge takes place after 9/10 of the thrust and consequently the compression starts after 1/10 of the return stroke ldoc duke has been completed, or in other words, the compression extends to 9/10 of the race. It is evident that, by replacing the usual discharge valve with exhaust ports or slots in the cylinder, all the losses of dispersion on the exhaust ldoc duke valve and all dead volumes and surfaces of washing, which necessarily come from the use of a discharge valve dedicated, are avoided. The diagram indicator (Figure 3) shows un'adiabatica of saturated steam for the expansion line and un'adiabatica of superheated ldoc duke steam for the line of compression.
This is the best proof of the excellent thermal action of this engine. The excessive initial condensation, in an engine in the ordinary counterflow fed saturated steam, makes sure that the expansion line follows approximately the law of Mariotte. In the engine A-flow, using saturated ldoc duke steam, there is almost no initial condensation, so the line expansion resulting necessarily un'adiabatica and even more if the supply steam is superheated. Due to adiabatic expansion, the dry fraction of the steam after the expansion is very low. Therefore, in the case of steam having an initial temperature of 300 C

We have already seen that the thermodynamic cycle of the Hummingbird consists of two adiabatic transformations and two isochoric transformations. In this post are analyzed the performance ultravent in the case of steam supply, ultravent even if this engine could exploit the expansion of the air, or in general of any gas. ENGINE DATA Hummingbird ultravent free piston monoeffetto Volume PMI PMI = V = 100 cc = 0.10 dm 3 volume at TDC TDC = V = 20cc = 0.02 dm 3 Compression ratio = 5: 1 OPERATING CONDITIONS Working fluid: Saturated steam at 10 bar (vaporization temperature: 179.9 C) Inlet pressure = P = 10 bar injection pressure at the exhaust Exhaust = P = 1 bar (atmospheric operation) ANALYSIS enthalpy of saturated liquid at 1 bar = H Liquid Saturated @ 1bar = 417.5 kJ / kg enthalpy of saturated steam at 10 bar H = Saturated Steam @ 10bar = 2777.1 kJ / kg Density of saturated steam at 10 bar = ρ Saturated Steam @ 10bar = 5.15 kg / m 3 below the flowchart in the PV plane.
Pressure at the end of adiabatic expansion: P Fine Adiabatic Expansion = 1.6 bar fraction of steam discharged PMS V = {- [(P * Exhaust SME V range) / P injection] (1 / gamma)} / V = PMS = {0.02 dm 3 - [(1 bar * (0.10 dm 3) 1.138) ultravent / 10 bar] (1 / 1,138)} / 0.02 = 0.339 dm 3 (33.9%) of 17 CORRECTION / 11/2012 (see note at end of post) Mass of steam consumed per cycle = m vap = Fraction of gas discharged PMS * V * ρ Saturated Steam @ 10bar = = 0.339 * 0.02 * 5.15 dm 3 kg / m 3 = 0.03492 ultravent g Heat supplied = m * vap (H Saturated Steam @ 10 bar - Liquid Saturated H @ 1 bar) = g * = 0.03492 (2777.1 kJ / kg - 417.5 kJ / kg) = 82, 4 J Work adiabatic expansion L = AB = 28.8 J Jobs in adiabatic compression CD = L = - 18.0 J Labor useful engine = AB + L L J CD = 28.8 - 18.0 J = 10, 8 J Efficiency ultravent = Work useful engine / Heat supplied = 10.8 J / 82.4 J = 13.1% efficiency Rankine (theoretical maximum ultravent with steam) = 16.6% of Carnot efficiency (theoretical maximum for any heat engine) = 17.7% COMMENTS With an operating temperature of 180 C hot that allows for saturated steam at a pressure of 10 bar and in the presence of atmospheric release, the theoretical yield of thermo-mechanical conversion of the Hummingbird ultravent is 13.1%. As the Carnot efficiency ultravent under the same conditions of temperature (T = 179.9 C hot and cold T = 99.6 C) that is 17.7% means that the engine pulls 74.0% of the theoretical maximum. Also by way of comparison, the performance of the Rankine cycle under the same conditions is equal to 16.6%. In this case the Hummingbird it is able to extract 78.9%. The useful work per cycle is 10,8J, a low value for a steam engine of 100cc displacement that operates with power to 10bar. Note however that the power developed, ie the work done in the unit of time, depends linearly on the operating ultravent frequency. Considering the constructional features of this engine is reasonable to assume that they are easily ultravent accessible operating frequencies of at least 50Hz (3000rpm) and in this case, the power would be amplified by 50 times (10,8J * 540W = 50Hz). CONCLUSIONS Hummingbird unite respectable performance in a device of extreme simplicity. This combination, absent in most of the external combustion engines, ultravent makes it particularly attractive to a potential practical use. CORRIGENDUM 17/11/2012 the formula previously given to evaluate the fraction of escaping vapor was wrong. Are shown below for possible comparisons. Fraction of steam discharged = 1 - (P Exhaust / P Fine Adiabatic Expansion) = 1 - (1 bar / 1.6 bar) = 0.375 (37.5%) All calculations employees have been revised and updated.
Hello Yuz, The isochores are always irreversible transformations in theory, that deadweight losses. In the Stirling cycle is possible during the isochoric keep and transfer the heat of isotherms through the regenerator. In the Brayton cycle to adiabatic interrupted and in the Ericsson cycle (two isobars and two isochoric), recovery is possible against-heat in the exhaust gases. In the case of the Hummingbird, the isochoric BC is still minimal ultravent loss but it is absolutely essential because it is responsible for the escape of steam expanded through the valve end lights. In practice, we save the building and the movement of the valve, the heart and soul of Uniflow. ultravent Very important however is the loss that occurs ultravent thermo-dynamic nell'isocora DA, one that allows the filling

The adiabatic transformation The adiabatic expansion of the vapor in the Mollier density of air tab


The adiabatic transformation The adiabatic expansion of the vapor in the Mollier density of air table diagram The isobaric transformation The vapor pressure of water The isothermal transformation The transformation isochoric The density of water The engine Manson free piston double-acting engine Manson free piston - Episode 07 Density of water vapor side considerations
The first post dedicated to the world of the motors to the liquid-vapor phase transition was that relating to the vapor pressure of water. The graph shown PT at this juncture can be used to determine if the water vapor is in its saturated state: the steam is saturated when its temperature and its pressure are those of a point on the curve of the vapor pressure as a function temperature. For convenience, below is the graph mentioned.
As already seen, the adiabatic expansion of an ideal gas causes a lowering of its pressure and its temperature. The saturated steam has a similar behavior as pressure and temperature decrease in the expansion adiabatic, but presents a fundamental difference: the process of adiabatic expansion of the saturated steam is accompanied by a partial condensation of the vapor. This phenomenon gives off heat and makes sure that the pressure and the temperature decrease less rapidly than a similar expansion of a gas. In this post is presented a numerical approach / experimental which allows to determine the trend of the pressure and of the condensed density of air table fraction as a function of the degree density of air table of expansion of the steam. INITIAL STATE The state of departure from which begins the expansion is known and is constituted by a certain amount of saturated steam at a defined pressure and temperature (P T initial and initial). The following equations are valid for the more general case in which there are both phases (liquid and vapor) and are then reported to the specific case in which the condensed fraction is absent in the initial state. m = m + m initial liquid saturated vapor saturated vapor initial initial m = (1 - Fraction condensed initial) * m = (1 - FC) * mm = initial liquid fraction condensed initial * m * m H = FC saturated steam @ initial P (T initial) = H vap sat in PRINTOUT = ρ saturated steamP initial (initial T) = ρ vap sat in PRINTOUT = HP initial liquid (initial T) = H liq in PRINTOUT = ρ fluidP Home (initial T) = ρ liq = PRINTOUT density of air table then in the enthalpy density of air table and internal energy of the initial state appear to be H = H * m vap sat in saturated steam at initial liq + H * m initial liquid = = H vap sat in * m * (1 - FC) + H in liq * m * FC U = H + P * V = = H + P * (m saturated vapor Home / ρ + m vap sat in liquid initial / ρ liq in) = = H + P * [(1 - FC) * m / ρ sat in vap + FC * m / ρ liq in] In the case where the initial state is constituted only by steam the condensed density of air table fraction density of air table is zero and the general equations given just met are simplified in H = H vap sat in * m U = H + P * V = H + P * m / ρ vap sat in STATE FINAL To effect the process of adiabatic expansion a part of the steam condenses. The liquid form is in addition to the possible condensed fraction already present in the initial state. The final state can then be represented as follows. m = m + m initial liquid saturated vapor saturated vapor final final m = (1 - Fraction condensed final) * m = (1 - FC fin) * mm = final liquid fraction condensed final * m * m H = FC since saturated steam @ P end (T end) = H vap sat right PRINTOUT = ρ saturated steamP final (final T) = ρ vap sat right PRINTOUT = HP liquid end (T end) = H liq since PRINTOUT = ρ fluidP final (final T) = ρ liq = PRINTOUT since then the enthalpy and internal energy of the final state since become H = H vap sat right * m * (1 - FC fin) + H * m * FC liquidation density of air table since since since U = H + P from the right fin = V * = H + P from the right * (m vap sat right / ρ vap sat far from the liq + m / ρ liq fin) = = H + P from the right * [(1 - FC final ) * m / ρ vap sat far from the FC + * m / ρ liq fin] Since in an adiabatic expansion, the relation L = -ΔU = - (since U - U) = U - U since knowing the value of work becomes possible to determine the amount of the condensed density of air table fraction. From the mathematical point of view it is convenient to adopt the linear approximation density of air table consists density of air table of assuming that the transformation curve on the plane PV equal to a line segment joining the initial state to the final one. In this case, the work volume is the area of a right-angled trapezium in which the height is given by the volume change, the larger base from the initial pressure and the minor base of the final pressure L = (P + P fin) * (since V - V) / 2 = = (P + P fin) * [(m vap sat right / ρ vap sat far from the liq + m / ρ liq fin) - (m vap sat in / ρ vap sat in + m liq

a house with passive housing, with three months of rain and clouds tea light food warmers no longer


Hello everyone, as the title my problem is condensation and therefore mold all over the walls of my apartment perimeter exposed to the outside. tea light food warmers Being on the top floor and having exposed on three sides of the house you can imagine ... The amount of condensation that in the bedroom (facing north), I often find the wet floor and the walls that are inevitably colonized by molds , especially in proximity of the corners at the top, the doors-windows and behind furniture, (detached from the wall also more than 10cm). During the cold winter days we leave the windows open in the bedroom for hours and hours (in camera), in the hope that the change of air contrasts the formation of mold, but all in vain. In the same room and in the kitchen do not talk about ... Because I'm tired of pouring liters of bleach from November to April and the only internal insulation of walls is not an ideal solution, I was wondering if the application under the plaster of a system radiant tea light food warmers heating + coat inside, might be a solution to the problem of condensation and mold. We have two small children and the situation is becoming untenable, any more than good advice and I accept, thank you all in advance.
First point: tea light food warmers ventilate properly! the moisture tea light food warmers you create the family and when you're at home, breathing, cooking, showers ... every two hours you should open a whole 15 minutes, tea light food warmers day, night, rain sun ... if you do not open the moisture remains inside. if you leave closed 4 hours straight can crear problems such as too much moisture if you leave a row now open in the winter it creates others as too cool walls mold grows best with humidity above 70% and temperature of the wall (surface) around 13-15gradi

Thanks for the Vs. answers. In winter, the walls are always cold, regardless of the fact that I leave the windows open or not. In truth I let air out for a long time to go away the bad odor that persists especially in the bedroom, which I think is linked to the mold or do not know what ... The apartment in 2006, we have already delivered false ceiling because they said it was too high, the close of the ground floor has the same problem. The windows are double glazed with wooden air chamber (during the winter always wet), we do not have plants inside and stretch it into the house. In late winter we remember to turn the mattress for the change from the summer to winter and in practice, the side that was facing the floor was wet and the feet of the bedside tables had become even green.

The radiators are not always running, go at set times, say about 10-11 hours a day. To get to 23C off, unfortunately I can not remember at what temperature they share.

Of course, the step was then very short, in practice many laboratories in many thought they had found in the cavitation bubbles subject to the "microscopic nuclear shaped charges", provided that the gas inside temperature si unit the bubbles contained substances whose nuclei could give nuclear reactions when they undergo the shock wave of cavitation and to its high temperature. Unfortunately experiments Diebner and Gerlach had not been sufficiently well known, so this idea of "microscopic nuclear shaped charges" was in fact a rediscovery of ideas Diebner and Gerlach.
Cardone makes a mistake in interpreting the experiments Diebner, at least as seen from the text of R. Karlsch, H. Petermann - Für u. wider "Hitlers Bombe" Waxmann, 2007. Cardone used (or attempted to use) the shock wave caused temperature si unit by chemical explosives (dynamite, according to Cardone) to reduce the volume of a sphere of nuclear fuel subcritical and make sovracritico, a technique now widely applied, as you know. The shock waves are used exclusively to reduce the volume of a nuclear explosive, a purely mechanical process that does not involve the nuclei, completely unrelated to what is happening around. Cardone passes arbitrarily enforced by the contraction of a metallic crystal lattice energy to situations much more extreme, those necessary to collide two nuclei of deuterium, causing it to melt, can not be obtained for sonocavitazione, as the repeated failures of Taleyarkhan have shown. Once again you come across an error of assessment of concentrations of energy; this di ff we have grown accustomed, a kind of systematic error. They are able to calmly confront a horn with a particle accelerator. In mid-January I will have the item Diebner of 1962 and I can give precise details about what he was able to accomplish during the war.
But you, Gabrichan, in your first experiments verify that the sulfur is not there? In any object involved in the experiment? And then, with regard to environmental contamination, what can you say? Have you a cleanroom ISO 1 in the basement?
No I do not have a cleanroom ISO1 in the basement, but not knowing the nature of the experiments that I do and the results is interesting to note that you asked questions. The answer is simple, however, depends on the amount, it is obvious that if there is only a few ppm at the end of the synthesis material of the doubt that there is some contamination there may also be, but if the resulting material is 30% of the material origin, and a few tenths of a gram, maybe the question is not there and even with a fairly spartan type of analysis is sufficient to reveal something, temperature si unit without resorting to sophisticated equipment. However S.Natale also good to you :)
To me, however, wonder if the same pan used for expressing the afternoon of Nuclear Physics of the border have content until lunch cabbage or onions. Obviously, then, to find the sulfur! Anyway, senz'analisi before and after "experiments" are totally inconclusive results: it is totally unnecessary to discuss and even would be taken into consideration. Very funny is the idea of "reaction" nuclear K - O = Na, note that the minus sign is not a typo. Appearance with anxiety that occur in the laboratory temperature si unit as well the reactions p * Be (9) = Be (9) and Fe (56) / He (4) = Al (14) so as to complete the arithmetic nuclear. The discovery of Al (14) would be perhaps the Nobel Prize?
I really do not grab the funny side? You, too, not joking: I tracked down on energeticambiente a discussion in which you say you've been experimenting with "an electrode for welding cast iron" and the "nails". I can make myself an experiment with a handlebar of a bicycle and an iron welded?
We come to the point of humor. 1) Reasoning of Mondaini "azzurini-green crystals, and CuSO4 or CuSO3." temperature si unit Now, I just take a ride on en.wikipedia to find other fourteen (14) of compounds of the Cu-green azzurini. As he did, to view, to recognize all of the CuSO4 is amazing! Yeah, because among those 14 is also, incidentally, Cu (OH) 2 CO 3 and Cu. Do not you say anything? Hint: it is employing an aqueous solution of K2 CO3.
2) S and Na are naturally present as impurities nell'H2O used in K2CO3 and Cu (as indeed shows Mondaini in another video). In addition, for washing glassware I think he used some detergent, which-coincidentally case - contain their Na and S. Then, the electrodes of Cu are perhaps those who smanazzato as you can see in the video? If you have used gloves, with what has come in contact? These questions must let you all, because I have the impression that you are a bit 'too much sport in conducting the experiments. But most of all, do you really think that by evaporating a

There may be different types of cooling tower: induced, afatek with fans in suction force, with fans in flow counter afatek flow, with flow of water and air in countercurrent cross-flow, with flow of water and air cross-flow
Compared to a traditional radiator, the efficiency is increased, as the case of direct afatek exchange, is also exploited the effect of evaporation of the water itself, thereby taking advantage of the latent heat of evaporation.
The reference parameter so there is the ambient temperature, but the tramadol shipped cod ambient wet bulb temperature, or the temperature that we can determine with the psychrometric chart, afatek knowing the ambient temperature and relative afatek humidity.
The ambient temperature is usually from 4 C to 6 C (or even higher values) less than the ambient temperature, then a cooling tower, allows to cool the water, at a temperature below the ambient temperature.
Furthermore, by exploiting the latent heat of evaporation, there is a considerable afatek increase of efficiency, in fact, we must consider that on average for each kilogram of http://beritabaik.web.id/overnight-canadian-cialis evaporated water, it has a dispersion of 600 Kcal / h (average). This implies of course that gave us an evaporative cooling tower, afatek by its very nature, consumes water, therefore we can not consider the circuit of a cooling tower as a closed circuit, in fact there is a constant water consumption, linked to potential dissipated.
where: Qc is the amount of water consumed afatek expressed inKg / P h is the heat capacity of the tower expressed in Kcal / h 600 is the amount of heat from aspportata generic cialis salt each pound of water evaporated (Kcal / Kg) ... average value coretto should be noted from the diagram of the steam, according to the actual operating conditions, but in the phase of find cialis cheap first approximation, this value allows a good accuracy, also in function of what we will define below. afatek
The drag losses, with the current drift eliminators, take on an almost irrelevant, it comes to losses amounting to about 0.1 to .05% of the total value of the recirculating flow.
The amount afatek of water purge, instead depends afatek on several factors: the quality of makeup water type of conditioning is applied to water cycles good choice generic levitra professional concentration
In any case, due to the continuous evaporation of water, we will have a phenomenon of gradual concentration, which will also bring a good starting water, to a state not acceptable from cooling circuits, which will oblige to reinstate, purge and condition.
Beyond a detailed discussion of these aspects we say that in a first approximation, especially if you have to make some considerations on water consumption of a tramadol no prescription needed cooling system, afatek we can consider the scope of the best choice female viagra salt water purge equal to the flow rate of water lost er evaporation. For brevity, therefore we can say that the average consumption of water in a cooling tower is given by the sum of the losses of water by entrainment plus twice evaporation losses.
Proper and careful management afatek of the plant, which was completed by the implementation of an effective water conditioning system, will improve as a result of such consumption.
To quickly complete the picture of this brief discussion, we say that an air-conditioning water from a cooling tower must be complete: product dispersing antifouling with its metering pumps product algaecide with reltiva dosing pump solenoid http: // islandlifestyle.ca/cialis-uk-suppliers automatic purge conductivity meter and a probe control unit
