A combination air cooler and dehumidification unit receives outside ambient air at 35°C, 100 kPa, 90% relative humidity. The moist air is first cooled to a low temperature T2 to condense the proper amount of water, assume all the liquid leaves at T2. The moist air is then heated and leaves the unit at 20°C, 100 kPa, relative humidity 30% with volume flow rate of 0.01 m3/s. Find the temperature T2, the mass of liquid per kilogram of dry air and the overall heat transfer rate.
