(meteorology)
Isobaric wet-bulb temperature, that is, the temperature an air parcel would have if cooled adiabatically to saturation at constant pressure by evaporation of water into it, all latent heat being supplied by the parcel.
The temperature read from the wet-bulb thermometer; for practical purposes, the temperature so obtained is identified with the isobaric wet-bulb temperature.

wet-bulb temperature

The temperature of a thermometer in which the bulb is enclosed in a wick that is kept moistened.

wet-bulb temperature

wet-bulb temperature
The lowest temperature at which air may be cooled by the evaporation of water at a constant pressure. It is measured with a wet-bulb thermometer.

The cooling tower model employs a 5th-order polynomial with 27 coefficients that relates the Approach (defined as the temperature difference between the water temperature leaving the cooling tower and the ambient wet-bulb temperature) to the airflow rate ratio (defined as the ratio of the air-flow rate to the maximum airflow rate), the water flow rate ratio (defined as the ratio of the water flow rate to the maximum water flow rate), the range temperature (defined as the inlet water temperature minus the outlet water temperature), and the inlet air wet-bulb temperature.
The floating head pressure controller controls head pressure to a constant degree of approach to the dry-bulb temperature for air-cooled condensers and to the wet-bulb temperature for evaporative condensers.
