As shown in the figure below, moist air at T = 34°C, 1 bar, and 35% relative humidity enters a heat exchanger operating at steady state with a volumetric flow

rate of 10 m3/min and is cooled at constant pressure to 22°C. Ignoring kinetic and potential energy effects, determine: ) the dew point temperature at the inlet, in °C. b) the mass flow rate of moist air at the exit, in kg/min. (c) the relative humidity at the exit. (d) the rate of heat transfer from the moist air stream, in kW.
