A cylinder is fitted with a frictionless piston contains 10 lbm of R-134a at 100 Psia, 300 F. The system is cooled at constant pressure until it reaches a quality of 25%. Determine:
a) The work in Btu for this process. Is the work done by the system or done on the system?
b) The heat transfer for this process, and
c) Show this process on a T-v diagram with respect to the saturation/actual temperature values.
