Air enters a dehumidifier/air-conditioning system with a mass flow rate of 60 kg dry air/min. the entering air is at 26°c, 50% relative humidity. saturated air and condensate leave the cooling section at 4°c. the air is then heated to a final temperature of 20°c in the heating section. determine: a.) the rate heat is removed in the cooling section, kj/min and tons b.) the rate water is condensed in the cooling section c.) the rate of heat transfer to the air in the heater section, kw d.) the relative humidity of the air exiting the system
