Expansion valves are designed to produce a pressure drop from 15 bar to 1 bar for saturated liquid water and air, respectively, as shown in Figure Q1. The inlet temperature of both working fluids is 198.3C Fig. Q1 You may assume: The air is an ideal gas; Both valves are well insulated; Both valves may be modelled as an open (ie. control volume) system at steady state; Potential and kinetic energy changes are negligible. Specific gas constant for air, R=0.287kJ/kgK
