Consider the evaporator section of an air-conditioning system (note: the evaporator may be considered as a shell and tube heat exchanger with refrigerant flowing through the tube and air flowing through the shell). air enters the evaporator at 32◦c and 1 bar with a volumetric flow rate of 50 m3/min and exits at 22◦c and 0.95 bar. refrigerant 134a at 5 bar with a quality of 20% enters the evaporator and leaves at 20◦c at the same pressure. assume steady state operation, negligible heat transfer at the outer surface of the heat exchanger, and negligible kinetic and potential energy effects. also, assume the air behaves as an ideal gas with constant specific heats. determine
