The wet-bulb temperature is the temperature a parcel of air would have if it were cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat being supplied by the parcel. A wet-bulb thermometer will indicate a temperature close to the true (thermodynamic) wet-bulb temperature. The wet-bulb temperature i...

The temperature of the wet thermometer bulb in a wet and dry bulb hygrometer. The wet bulb is surrounded by wet fibres and evaporation of water from the fibres cools the wet bulb. The rate of evaporation depends on the relative humidity of the air.

The temperature at which water, by evaporating into air, can bring the air to saturation at the same temperature. Traditionally this was the temperature indicated by a thermometer whose bulb is wrapped in a wet sheath. The wet bulb temperature and the dry bulb temperature (i.e air temperature) would then be used to calculate relative humidity or de...
