Problem 12.033 SI
As shown in the figure below, moist air at T1 = 36°C, 1 bar, and 35% relative humidity enters a heat exchanger operating at steady state with a volumetric flow rate of 10 m5/min and is
cooled at constant pressure to 22°C. Ignoring kinetic and potential energy effects, determine:
(a) 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.
