 To analyze the influence of different process parameters on expander operation, to calculate its specific work, the formula [1] can be used:

formula7.9.eng

where k —an adiabatic indicator; R — a gas constant, kJ/(kmole×K); рin and рout — gas pressure at the expander inlet and outlet, accordingly, MPa; Z — a factor, considering “the reality” of gas.
