7. 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: Bmix X i X j yiyjBij where the virial coefficients for the pure species, Bii and Bjj, are determined from Equation 5.3-6 and Bij 0:5 Bii Bjj.
