    The atmospheric air at 30°C dry bulb temperature and 75% relative humidity enters a cooling coil at the rate of 200 m 3 /min. The coil dew point temperature is 14°C and the by-pass factor of the coil is 0.1. Determine: i) The temperature of air leaving the cooling coil ii) The capacity of the cooling coil in kW iii) The amount of water vapour removed per min, and iv) The sensible heat factor for the process 2
