So9lve the below problem:
Q: 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.
