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?

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?
Psychrometric chart is not required.
