An air-conditioning system consists of a spray section followed by a reheater. Moist air at 32°C and 77% enters the system and passes through a water spray, leaving the spray section cooled and saturated with water. The moist air is then heated to 25°C and 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, in °C.
(b) the change in the amount of water vapor contained in the moist air passing through the system, in kg per kg of dry air. Locate the principal states on a psychrometric chart.
