Apiston-cylinder device initially refrigerant-134a at 100 kpa and 20°c. heat is now trans- ferred to the refrigerant from a source at 150°c, and the pis- ton which is resting on a set of stops, starts moving when the pressure inside reaches 120 kpa. heat transfer continues unti the temperature reaches 80°c. assuming the surroundings to be at 25°c and 100 kpa, determine (a) the work done, (b) the 8 heat transfer, (c) the exergy destroyed, and (d) the second-law efficiency of this process.
