- Refrigerant 134a Expands In A Piston Cylinder Assembly From P1 160lbf In2 And T1 140 F To P2 30lbf In2 And T2 80 F 1 (11.22 KiB) Viewed 46 times
Refrigerant 134a expands in a piston-cylinder assembly from p1=160lbf/in2 and T1=140∘F to p2=30lbf/in2 and T2=80∘F. The mass of refrigerant is 0.5lb. During the process, the work done by the refrigerant is 4.32Btu. Kinetic and potential energy effects are negligible. Determine the initial volume of the refrigerant, V1, in ft3, and the heat transfer for the process, in Btu.
