3. In an adiabatic cooling tower 500 kg/min hot water, is to be cooled from 50°C to 35°C by using air with 25°C dry bulb temperature and 15°C wet bulb temperature. The air leaves the tower with 32°C dry bulb temperature and 85% relative humidity. a. Show the points of inlet and outlet air on the PSYCHROMETRIC chart given below. Read the followings: Absolute humidity and Relative humidity of the inlet air. Absolute humidity and wet bulb temperature of the exit air. b. Calculate the volumetric flow rate of the air used. c. Why do we use cooling towers in process plant?
