Air enters a natural draught cooling tower at 1.013 bar and 13 °C and relative humidity 50%. Water at 60°C from turbine condensers is sprayed into the tower at the rate of 22.5 kg/s and leaves at 27 °C. The air leaves the tower at 38 °C, 1.013 bar and is saturated. Calculate: (i) the airflow required in cubic metres per second; (ii) the make-up water required in kilograms per second. Assume water is supplied outside the tower
