A cylinder fitted with a piston contains 10 lbm of R-134a at 100 psia and 140 degree F. The refrigerant is cooled at constant pressure until it exists as a saturated fluid with a steam quality of, x = 60%. (a) Determine the boundary work and the heat transferred to/from the refrigerant. (b) If the surroundings are at 15 psia and 75 degree F, determine the entropy generated by this process, the exergy destroyed, and the second law efficiency. Will this process actually occur?
