      3 A 20 ft3 rigid tank contains saturated regrigerant-134a vapor at 160 psia. As a result of heat transfer from the refrigerant, the pressure drops to 50 psia. Show the process on a P-v diagram with respect to the saturation lines, and determine (a) the final temperature, (b) the amount of refrigerant that has condensed, and (c) the heat transfer.

      Table A-1E gives the gas constant for air as R = 0.3704 psia∙ft3/lbm∙R. The mass that left the tank is simply the difference between the initial and final mass: mout = m1 – m2 = 20.95 lbm – 8.38 lbm = 12.57 lbm. We can use the ideal gas properties for air from Table A-17E. Since T1 = T2 = Tout= 120oF = 579.69 R, we have u1 = u2 =98.90 ...
