zpPGE 312-SPRING 2008 Physical and Chemical Behavior of Petroleum Fluids I Homework 2 Problem 2-1 . Normally, we neglect the pressure of the liquid. Therefore, P=17 Psia for 2-methylpentane at 150 , from Figure 2.8 in text book. Problem 2-5. Matching plots above Process Description From 1-2 Phase change from gas to liquid as the vapor pressure curve is crossed. From 2-3 Smooth transition from liquid to gas as we move above the critical point. From 3-4 Gaseous phase. From 4-1 Gaseous phase.
