quations. Partial credit will be awarded on careful and Problem (1) Refrigerant 134a initially at 1200 kPa and 46.32 C is contained in a Diston-cylinder device fitted with stops. The fluid is heated at constant pressure until it mas quality of 0.6 and the piston reaches to the stops. Then the fluid continues to be heated until the pressure is 1600 kPa. a) (10 points) On the T-v diagrams sketch, with respect to saturation line, the pressure curves passing through initial, intermediate, and final states of the Refrigerant 134a. b) (10 points) Find the quality of Refrigerant 134a at the final state. c) (15 points) Find the overall change in internal energy between the initial and final states per unit mass of Refrigerant 134a. d) (15 points) Find the amount of heat transfer to the piston-cylinder system per unit mass of Refrigerant 134a.
