Extracted text: Refrigerant R 134 a enters an adiabatic heat exchanger at 140 kPa with a quality of 40% and a flow rate of 0.033 kg/s and leaves as saturated vapor at the same pressure. While Air inters the heat exchanger at 100 kPa and 25 °C with a volume flow rate of 0.1 m /s. Considering air as ideal gas with constant specific heat, Find: a) Exit temperature of air in K b) Rate of entropy generation for the process in kW/K
