Sketch an induced draft counter-flow cooling tower, showing how it may be regulated to control the operation of a refrigeration plant. A cooling tower functions in atmospheric conditions of 23°C db (dry bulb), 17°C wb (wet bulb), cooling 15 kg/s of water from 27°C to 21°C. The air is assumed to leave the top of the tower at 25°C saturated with water. Fan air power input is 5kW. a. b. C. Find the air mass flow induced by the fan for the given cooling duty. Find the evaporative loss (%). Find the make-up water required, taking into account that some moisture is gained by the cooling air.
