1 PGE 312 - SPRING 2006 Physical and Chemical Behavior of Petroleum Fluids I Test #2, 50 Minutes Closed Book Note: It will be in your best interest to attempt all the questions. Please budget your time accordingly. Problem 1 ( 25 points ) Two hundred pound moles (200 lb moles) of a real gas mixture consisting 90 mole% of methane and 10 mole% of ethane are confined in a vessel at P = 3023 psia and T = 86 F. ˚ Calculate the volume of the gas in cubic feet. Please do not assume ideal gas behavior.
