Temperature that is measured by a wet-bulb thermometer, which has a wet cloth sleeve that covers its bulb. Wet-bulb temperature and dry-bulb temperature are used to compute relative humidity.
A wet bulb temperature of air is used to evaluate the humidity in the air. It is obtained with a wet thermometer bulb to record the evaporation rate with and airstream passing over the bulb to help in evaporation.
Temperature read on a thermometer whose bulb is covered by a film of water or ice and which is exposed to the air in a position sheltered from direct solar radiation.
is used in psychrometry and is the temperature recorded by a thermometer whose bulb has been covered with a wetted wick and whirled on a sling psychrometer. Taken together with the dry-bulb temperature, it permits determination of the relative humidity of the atmosphere.
The lowest temperature that can be obtained on a wet-bulb thermometer in any given sample of air. Obtained by evaporation of water (or ice) from the muslin wick. Used in computing dew point and relative humidity.
The temperature of a gas stream taken with a wetted thermometer. It is approximately equal to the adiabatic saturation temperature of the gas.
Technically, the temperature registered by the wet bulb thermometer of a Psychrometer. It is the lowest temperature to which air can be cooled by evaporating water into it at a constant atmospheric pressure.
Wet-bulb temperature is a factor in the determination of relative humidity. Wet-bulb temperature is measured using a thermometer that has its bulb wrapped in cloth—called a sock—that is kept wet with water via wicking action. Such an instrument is called, not surprisingly, a wet-bulb thermometer.
