Atmospheric air at 90o F and 60% relative humidity flows over a cooling coil at an inlet volumetric flow rate of 2000 ft3/min. The cooling coil temperature is 40oF. The liquid condensate is removed from the system at 60o F. The air is then reheated until a final state of 80 oF and 40% relative humidity is reached. Determine:
a. The mass flow rate of the condensate leaving the unit.
b. The heat transfer rate in the cooling section.
c. The heat transfer rate in the reheat section.
