QUESTION 16 – COOLING TOWERS AND EVAPORATIVE CONDENSERS Water flows at 5000 kg/h and 40°C into a cooling tower and is cooled to 26°C. The unsaturated air enters the tower at 20°C with a relative humidity of 0.4. It leaves as saturated air at 30°C. The pressure is constant at 1 bar throughout. Calculate (a) the mass flow of air per hour. (b) the mass of water evaporated per hour.
