A cooling tower receives 6 kg/s of water of 60oC. Air enters the tower at 32oC DB and 27oC WB temperatures and leaves at 50oC and 90 per cent relative humidity. The cooling efficiency is 60.6 per cent. Determine: (a) the mass flow rate of air entering, and (b) the quantity of make-up water required.
