Chapter 5, Problem 5.77P

Methanol is to be delivered to a process unit at a rate of 15.0 kmol/h by a stream that is 30.0 mole methanol and 70.0 mole% propane. Estimate the volumetric flow rate of this stream at 10.0 atm and

100.0°C using the truncated virial equation and the following mixing rule:

   $B_{\text{mix}}={\displaystyle \underset{i}{\sum }{\displaystyle \underset{j}{\sum }{y}_i{y}_j{B}_{ij}}}$

where the virial coefficients for the pure species. B_iiand B_jjare determined from Equation 5.3-6 and

   $B_{ij}\approx 0.5\left(B_{ii}+B_{jj}\right)$.
