3. A piston-cylinder device contains 10 lbm of R-134a at 160 psia and 220 degrees F. The refrigerant is now cooled at constant pressure until it becomes a saturated liquid. If the ambient conditions are 14.7 psia and 65 degrees F, determine: a. The boundary work and the heat transfer associated with this process. b. The change in entropy and the entropy generated by this process. c. The exergy of the refrigerant at the initial state and the exergy destroyed. d. Is this process possible?Explanation / Answer
