An air-conditioning system consists of a spray section followed by a reheater. Moist air flowing at the rate of 1.5m3/s at 32oC and relative humidity 77% enters the system and passes through the water spray, leaving the spray section cooled and saturated with water. The moist air is then heated to 25oC and relative humidity of 45% with no change in the amount of water vapor present. For operation at steady state, determine:

(a) the temperature of the moist air leaving the spray section. 

(b) the amount of water added by the spray.
