In a humidifi er, air at a dry bulb temperature of 40C and relative humidity of 10% is humidifi ed to a relative humidity of 40%. Determine the amount of moisture added in the humidifi er per kg of dry air.

Air at a dry bulb temperature of 100C and 4% relative humidity is passed over cooling coils to cool it to a dry bulb temperature of 40C. How much heat is removed from the air in the process?
