The air at 35° C dry bulb temperature and 25° C wet bulb temperature is passed through a cooling coil at the rate of 280 m/min. The air leaves the cooling coil at 26.5° C dry bulb temperature and 50% relative humidity. Find: 1. Capacity of the cooling coil in tonnes of refrigeration; 2. Wet bulb temperature of the leaving air; 3. Water vapour removed per minute ; and 4. Sensible heat factor.
