At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature); at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling.
Learn the difference between dry bulb, wet bulb, and dew point temperatures and how they relate to humidity and heat transfer. Find out how to measure and calculate these temperatures using formulas and examples.

Learn how to calculate the wet-bulb temperature from air temperature and relative humidity using the Stull formula. Find out the applications of wet-bulb temperature and Wet-Bulb Globe Temperature in meteorology, construction, and health.
21 Απρ 2009 · The dry bulb temperature is the ambient air temperature that is measured by regular thermometers, while the wet bulb temperature is measured by thermometers that are wrapped in wetted wicks. The greater the wet bulb depression, the greater the felt effect is on the discharge air temperature.
Wet bulb temperature is the lowest temperature to which air can be cooled by the evaporation of water into the air at a constant pressure. It is therefore measured by wrapping a wet wick around the bulb of a thermometer and the measured temperature corresponds to the wet bulb temperature. The dry bulb temperature is the ambient temperature.
