1 HOMEWORK 3 02.05.2011 1- Air at 1 atm, 15 C, and 60 percent relative humidity is first heated to 30 C in a heating section and then passed through an evaporative cooler where its temperature drops to 25 C. Determine a) The exit relative humidity b) The amount of water added to air, in kg H 2 O / kg dry air. 2- On a summer day in New Orleans, Louisiana, the pressure is 1 atm; the temperature is 32 C; and the relative humidity is 95 percent. The air is to be conditioned to 24 C and 60 percent relative humidity. Determine the amount of cooling, in kJ, required and
