An air-conditioning unit inducts outside air at 46° C (114.8 F) and 100 kPa having a relative humidity of 16%. The air is cooled and dehumidified to provide an outlet temperature of 29° C (84.2 F) and relative humidity of 39%. The coefficient of performance for the vapor-compression refrigeration system contained in the air conditioning unit is 2.92.

Determine the following quantities:

A. The mass of water removed per unit mass of dry air

B. The cooling rate per unit mass of dry air

C. The input power to the vapor-compression refrigeration system per unit mass of dry air
