Problem 2 Refrigerant-134a is throttled from saturated liquid state at 800 kPa to a pressure of 120 kPa. Determine the temperature drop during this process and the final specific volume of the refrigerant. Draw a schematic of the throttling valve and show mass and energy interactions across the control volume. List any necessary assumptions as they arise and show that the throttling valve can be considered isenthalpic.

Problem # 1 An isolated cylinder-piston system is connected to a supply line through a valve. The supply line conditions are P= 600 kPa and T= 100 C. Initially, the cylinder contains 0.1 m of air at 150 kPa and 30 C. when the valve is opened, air enters the cylinder and the piston is slowly pushed upwards until the final volume is twice the initial volume. If the specific heats are taken as constant, determine: a. Final temperature in the cylinder b. Mass of air that entered the cylinder.
