The air in a building is to be maintained at 25C and 55% relative humidity by passing outside air through a water spray. The air enters the spray chamber at 32C and 70% relative humidity, leaves the chamber cooled and saturated with water vapor, and is then reheated to 25C. Estimate the temperature of the air leaving the spray chamber and the water (kg) added to or removed from (specify which) each kilogram of dry air processed.
