Air enters a window air conditioner at 1 atm, 32C, 70% relative humidity at a rate of 2 m^3/min, and it leaves as saturated air at 15C. Part of the moisture in the air that condenses during the process is also removed at 15C. Determine the rates of heat and moisture removal from the air in KJ/min and kg/min respectively.
