In previous posts, we evaluated the mechanical potential energy of an ideal gas and how it is distributed in the two isobaric and adiabatic contributions. The calculation was possible because the behavior of an ideal gas is described by simple mathematical equations and therefore it is possible nolan smith duke to analytically solve the problem. In the case of steam analysis is more complex in that its behavior can not be described by general equations simple and it becomes necessary to refer to the experimental values tabulated. This operation allows to build even for the steam the various graphics already introduced for the case of ideal gases. In the following figure shows the trend of the contribution in the adiabatic function of the pressure nolan smith duke ratio (Pmax / Pmin) for saturated steam. The same graph are also trends for the three types of ideal gas already discussed in the post titled mechanical nolan smith duke potential energy of gas - Part Two.
Note that for the steam have been represented two very similar trends between them which make reference to two different values of Pmin (in fuchsia color for Pmin = 1bar and light blue color for Pmin = 0,1bar). The picture shows that at constant pressure ratio the contribution adiabatic mechanical potential energy of the saturated steam is always greater than that of the gases. For the steam as the gases is possible to identify an optimal value for the compression ratio, defined as ratio between the volume at the end of adiabatic expansion (Vmax) and the volume at the beginning adiabatic expansion (Vmin), which allows complete expansion of the steam until the pressure Pmin. The graph below shows the trend of the compression ratio optimal function of the ratio for the saturated vapor pressure (at Pmin and Pmin = 1bar = 0,1bar) and trends relating to ideal gases.
As in the case of gas developments are of a straight line with equation log 10 (Compression Ratio) = (1 / gamma) * log10 (C Pressure Ratio) and the trend is close to linearity for saturated steam, you can do a rough estimate of its hypothetical coefficient range with this report range = log 10 (C Pressure Ratio) / log 10 (Compression Ratio) Plotting the value range calculated with the previous report as a function of pressure ratio we obtain the curves shown below.
