Extracted text: Moist air enters an air conditioning unit at 40°C dry bulb temperature and 45% relative humidity. The air is first passed over cooling coils to remove all of the moisture necessary to achieve the final moisture content and then is passed over heating coils to achieve the final conditions of 20°C dry bulb temperature and 10°C wet bulb temperature. The pressure remains constant at 1 atm throughout the process. (a) Sketch the psychometric diagram for the process. (b) Determine the dew point temperature of the mixture at the inlet of the cooling coils and at the inlet of the heating coils. (c) Calculate the net heat transfer for the entire process, in kJ/kg dry air.
