Wet-Bulb Temperature - an overview ScienceDirect Topics

Wet-Bulb Temperature - an overview ScienceDirect Topics

14.5.1 Wet bulb temperature, dry bulb temperature and cooling effectiveness. 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 ...

Air at 70 F will hold twice as much moisture as air at 50F. In the range of temperatures encountered in a greenhouse, for every 20 F rise in dry bulb temperature, the water-holding capacity of the air doubles, and the relative humidity is reduced by one-half. This relationship is important in managing humidity in the greenhouse.
