Outside atmospheric air with a dry bulb temperature of 90.0°F and a wet bulb temperature of 85.0°F is to be passed through an air conditioning device so that it enters a house at 71.0°F and 40.0% relative humidity. The process consists of two steps.

First, the air passes over a cooling coil, where it is cooled below its dew point temperature and the water condenses out until the desired humidity ratio is reached. Then, the air is passed over a reheating coil until its temperature reaches 71.0°F. Determine

a. The amount of water removed per pound of dry air passing through the device.

b. The heat removed by the cooling coil in Btu/(lbm dry air).

c. The heat added by the reheating coil in Btu/(lbm dry air).
