Air at 30 ºC with a dew point of 14ºC enters a textile dryer at a rate of 15.3 m3/min and leaves saturated. The dryer operates adiabatically. Use the psychrometric chart to determine the absolute humidity and humid volume of the entering air, and then use the results to determine the flow rate of dry air (kg/min) through the dryer, thefinal temperature of the air, and the rate (kg/min) at which water is evaporated in the dryer.
