(4 points) A-C line Liquid R-134a A rigid container containing 6.8 kg of saturated liquid R-134a at 26°C is used to fill an air- conditioning system. A valve is opened and allows liquid R-134a to escape the tank into the A-C line until only 0.85 kg of R-134a remains in the tank, at which point the valve is closed. During the process, heat transfer is allowed to occur to maintain the tank temperature at 26 °C. What is the quality...

A cooled, closed container holds Refrigerant 134a, initially at 0 °C and 59% quality. It has a safety valve that opens when the pressure inside reaches 5 bars. One night, the cooling system malfunctions, allowing the Refrigerant 134a to be heated until eventually the safety valve opens. What is the temperature of the Refrigerant 134a in the container when the valve first opens?

Refrigerant 134a enters a compressor with a mass flow rate of 15 kg/s with a velocity of 10 m/s. The refrigerant enters the compressor as a saturated vapor at 10°C and leaves the compressor at 1400 kPa with an enthalpy of 281.39 kJ/kg with a negligible velocity. The rate of work done on the refrigerant is measured to be 380 kW. If the elevation change between the compressor inlet and exit is negligible, determine the rate of heat transfer associated...
