Arigid tank of total volume 0.2 m^3 initially contains saturated vapor r-134a at an absolute pressure of 10 bar (state 1). a supply line connected to the tank via a valve contains r-134a at an absolute pressure of 14 bar and temperature of 60 c. the valve is opened until 0.1 m^3 of the tank is filled with saturated liquid r-134a while 0.1 m3 of the tank is filled with saturated vapor r-134a, both at an absolute pressure of 12 bar (state 2). (a) what is the quality (%) of r-134a at state 2? (b) determine the heat transfer (kj) during the process. indicate whether it is into the system or out of the system.
