In a fixed volume, 0.3 m³ container, initially there is refrigerant R-134a at 6 °C. Initially, 60% of the total mass is in the vapor phase and the remainder is in the liquid phase. The vessel is connected via a valve to a pipe through which R-134a flows at 1.2 MPa (1200 kPa) and 110 °C. Then the valve is opened and R-134a fluid flows slowly from the pipe into the container. When the pressure is 1000 kPa, all the refrigerant in the vessel is in the saturated vapor phase and the valve is closed at this point. By finding the final temperature in the container, indicate by thermodynamic analysis whether such a process can take place within the framework of the values given above?

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.
