A 0.3-m3 rigid tank initially contains refrigerant- 134a at 14°C. At this state, 55 percent of the mass is in the vapor phase, and the rest is in the liquid phase. The tank is connected by a valve to a supply line where refrigerant at 1.4 MPa and 100°C flows steadily. Now the valve is opened slightly, and the refrigerant is allowed to enter the tank. When the pressure in the tank reaches 1 MPa, the entire refrigerant in the tank exists in the vapor phase only. At this point the valve is closed. Determine (a) the final temperature in the tank, (b) the mass of refrigerant that has entered the tank, and (c) the heat transfer between the system and the surroundings.

A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40°C and an initial volume of 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. The process is then maintained by allowing the volume to change while the pressure is kept constant. At the end of this process, the temperature reaches 50°C. Assuming the state changes as if they are balanced,calculate;a) The mass of R-134a refrigerant in the system,b) The amount of heat transferred during the fixed volume process,c) The amount of heat transferred during constant pressure operation.d) Show the state changes on the P-v diagram.
