A stream of air at 37C and 50% relative humidity flowing at a rate of 1250kg / h is to be cooled to 15C and dehumidified in a spray tower. The air is saturated as it emerges from the tower. Liquid water leaves the tower at 12C ; some is withdrawn, and the rest is cooled and recirculated. No heat is transferred between the tower and its surroundings . Calculate the rate (kg / h) at which water must be withdrawn from the recirculation loop and the heat duty on the cooler (kW). (Suggestion Use an overall energy balance for the latter calculation)
