Air at 20°C dry bulb temperature and 10% relative humidity is passed through a spray of heated water. The air leaves at temperature of 30°C dry bulb temperature and a humidity ratio of 0.015 kg/kgDA. Determine the heat transfer rate and the percentage increase in relative humidity. The atmospheric pressure is 101.325 kPa. If the desired air needs to be heated to reach a relative humidity of 100%, what humidity ratio is necessary at the exit?
