Chapter 24, Problem 50P

The enthalpy of a real gas is a function of pressure as described below. These data were taken for a real fluid. Estimate the enthalpy of the fluid at 400 K and 50 atm $\left(\text{evaluate the integral from 0}\text{.1 atm to 50 atm}\right)$.

$H{\displaystyle {\int }_0^p\left(V-T{\left(\frac{\partial V}{\partial T}\right)}_p\right)dp}$
