Wet Bulb Temperature of Air (WBT): The wet bulb temperature of air is also measured by the ordinary thermometer, but the only difference is that the bulb of the thermometer is covered by the wet cloth. ... The difference between the DBT and WBT is called as wet bulb depression.

Dry Bulb Temperature and Wet Bulb Temperature
Dry bulb temperature refers to the temperature of the air measured by a thermometer that is not covered by any wet material. It is also known as the ambient temperature or air temperature.
On the other hand, wet bulb temperature refers to the temperature of the air measured by a thermometer wrapped with a wet cloth. As the water on the cloth evaporates, it causes the temperature to decrease.
Wet Bulb Depression
The difference between the dry bulb temperature and the wet bulb temperature is called the wet bulb depression. It is also referred to as the wet bulb temperature depression.
The wet bulb depression is a measure of the humidity of the air. The higher the humidity, the smaller the wet bulb depression. Conversely, the lower the humidity, the higher the wet bulb depression.
Significance of Wet Bulb Depression
The wet bulb depression is a critical parameter in the study of psychrometry, which is the study of the physical and thermodynamic properties of air-water mixtures.
The wet bulb depression is used to calculate a variety of important parameters, including:
- Relative humidity
- Dew point temperature
- Enthalpy
- Specific volume
In addition, the wet bulb depression is used in air conditioning systems to determine the cooling capacity and the efficiency of the system.
Conclusion
In summary, the wet bulb depression is the difference between the dry bulb temperature and the wet bulb temperature. It is an essential parameter in the study of psychrometry and is used to calculate various thermodynamic properties of air-water mixtures.
