Page 7 of 7 (c) Calculate the heat transfer during this process
(1->3). (2 points) (d) Drww the process en the T-v and P-v diagrame with respect to saburation line. (2 points) Page 6 of 7 Problem 4 (10 points) A mass of 2 kg of saturated mbxture of refrigerant (
R-134a) is cootained in a pidton-cylinder device at
0\deg C. Initially, 1.5 kg of the refrigerant is in the liquid phase and the 0.5 kg is in the vapor phase. Heat is now transferred to the refligerant, and the piston, which is resting on a set of stops, starts moving When the pressure inside reaches 400 kPa . Heat transfer continues until the total volume increases by 50 percent. Show all weur merk clearly, (a) Fill in the following table with all properties at states
