Question

A small-size cooling tower is designed to cool 6.5 litres of water per second, the inlet temperature of which is 45 deg.
c. The motor-driven fan induces 10 cubic. M/s of air through the tower and the power absorbed is 5 kw. The air entering the tower is at 20 deg. C, and has a relative humidity of 60%. The air leaving the tower can be assumed to be saturated and its temperature is 27 deg.
c. Calculate: (i) the amount of cooling water (make-up) required per second. (ii) the final temperature of the water. Assume that the pressure remains constant throughout the tower at 1.013 bar.
