| Jan 10, 2018 at 9:51 | comment | added | yolegu | The proposed integral cannot be calculated with a cubic equation of state which is a function of $T$ and $v$ but not $P$ and $v$. Thus derivative at fixed $P$ cannot be estimated. Regarding the two phase problem, my concern is more about how to estimate the enthalpy of the system when it is in vapor-liquid equilibrium and that we know the enthalpy of both phases. | |
