Evaluation of the thermodynamic differential ratios for an ammonia-water vapour mixture.

Author(s) : KAKATSIOS X. K., CHATZIDAKIS S. K., FLORATOS O. E., ROUVAS A. K.

Summary

The real gas isentropic change is often calculated by use of the ideal isentropic change equations with the isentropic exponent k taken as the local value of the constant pressure to constant volume (Cp/Cv) ratio of the Cp/Cv specific heat of the real gas isentropic change on the basis of the entropy function S= S(p,v,t) and the entropy variation condition shows that three new generalized isentropic exponents exist, which should be used in place of the conventional exponent k= Cp/Cv. Analytical functions are provided for the new exponents.
