Principles of Evaporative Cooling System - PDHonline.com

The wet bulb temperature is indicator of moisture content of air. Wet bulb temperature is very useful in evaporating cooling processes as the difference between the dry bulb and wet bulb temperature is a measure of the cooling efficiency. At relative humidity, the wet bulb temperature equals dry bulb temperature.
