Question: An equimolar n - pentane ( 1 ) / n - heptane ( 2 ) liquid mixture is flashed at 3 7 9 . 6

An equimolar n-pentane(1)/n-heptane(2) liquid mixture is flashed at 379.6mmHg and 325K. Saturation
pressures at this temperature are 1302.7mmHg and 152.7mmHg respectively. Analysis of the liquid
phase leaving the unit reveals that the flow rate for the liquid is 0.882molessec. What is the flow rate of
the mixture entering the flash distillation unit? What is the flow rate and composition of the vapor
leaving the flash distillation unit?
An equimolar n-pentane(1)/n-heptane(2) liquid mixture is flashed at 379.6mmHg and 325K.
