Air (cp = 1.0 kJ/kgK) enters an air conditioning system at 40C with a mass flow rate of 1.5 kg/s. The air is cooled by exchanging heat with a stream of R-134a refrigerant that enters the heat exchanger at -8C and 20% quality, and exits with 100% quality. If 25 kW of heat is transferred out of the air, determine: (40 pts) i) Mass flowrate of R-134a (kg/hr) ii) Exit temperature of air (C) iii) Exit pressure of R-134a (kPa)
