Wet-bulb temperature
The wet-bulb temperature is based on the psychometric measurement. Water evapo-
rating from the moistened wick on the wet-bulb thermometer cools the thermometer
bulb and lowers the temperature reading. The cooling effect of the evaporation from
the bulb depends on the amount of water vapor present in the air.
