Question

Refrigerant 134-a contained in a piston-cylinder assembly rapidly expands from an initial state where T1= 140◦F, p1= 200 lbf/in2 to a final state where p2= 5 lbf/in2 and the quality, x2, is (a) 99%, or (b) 95%. In each case, determine if the process can occur adiabatically. If yes, determine the work, in Btu/lbm, for an adiabatic expansion between these states. If no, determine the direction of the heat transfer.

Refrigerant 134-a contained in a piston-cylinder assembly rapidly expands from an
initial state where T1 = 140°F, p1
and the quality, x2, is (a) 99%, or (b) 95%. In each case, determine if the process
can occur adiabatically. If yes, determine the work, in Btu/lbm, for an adiabatic
expansion between these states. If no, determine the direction of the heat transfer.
= 200 lbf/in“ to a final state where
