Typically wet bulbs are used to give a heat-index or what it "feels like" outside. Because humans cool themselves by sweating, wet bulbs attempt to factor in humidity and wind speed to approximate the effective temperature while sweating. The wet bulb temperature is also used, together with the dry bulb temperature, to determine the relative humidity. If you know the relative humidity, you can calculate the difference with an equation given at:

What else can I help you with?
Is the wet bulb thermometer reading always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
Will the relative humidity be high if the wet-bulb depression increases?
No, the relative humidity will be low if the wet-bulb depression increases. Wet-bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature, and a higher wet-bulb depression indicates drier air.
What is the wet-bulb depression if the dry bulb is 20 and the wet bulb is 17?
The wet-bulb depression is 3°C (20°C - 17°C). It represents the difference between the dry-bulb temperature and the wet-bulb temperature, indicating the maximum potential cooling that can be achieved through evaporation.
Why did the wet-bulb temperature record a lower temperature then a dry-bulb temperature?
the evaporation off the moisture on the wet bulb absorbs the heat.
What main parts are to make a psychrometer?
A psychrometer consists of two thermometers: a dry-bulb thermometer and a wet-bulb thermometer. It also uses a wick or cloth that is moistened with distilled water to acquire readings. These components work together to measure relative humidity in the air.

Is The wet bulb thermometer reading is always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
Is the wet bulb thermometer reading always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
On a cold winter day the air temperature is 2C and the wet-bulb temperature is -1C What is the relative humidity at this location?
51%.... open to the Relative Humidity chart in the reference tables. the wet bulb temperature is -1C and the dry bulb temp. is 2C, making a difference of 3C. On RH chart, go down to 3C column (difference between the Wet bulb and dry bulb) until it intersects the dry bulb 2C. At this intersection is 51%

Will the relative humidity be high if the wet-bulb depression increases?
No, the relative humidity will be low if the wet-bulb depression increases. Wet-bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature, and a higher wet-bulb depression indicates drier air.
The difference between wet-bulb and dry-bulb temperature is called?
The difference between wet-bulb and dry-bulb temperature is called the Wet-Bulb Depression. It is a measure of air humidity, with a larger depression indicating higher humidity levels.
What are wet bulb and dry bulb?
The common thermometer for measuring body heat and outside temperatures are dry bulb thermometers. The wet bulb thermometer is modified with a wet cloth at the tip. The wet bulb thermometer may be attached to a string to swing it around through the air. The purpose of this would be to allow the bulb to cool off by allowing the water to evaporate. This effectively measures the air temperature after humidity effects. This stands to say that on humid days the wet and dry bulb temperatures are relatively similar and getting wet or sweaty won't significantly make a person feel cooler. This follows the theory of psychrometrics taught by Professor Samuelson of the department of Mechanical and Aerospace Engineering at the University of California, Irvine.
What is the wet-bulb depression if the dry bulb is 20 and the wet bulb is 17?
The wet-bulb depression is 3°C (20°C - 17°C). It represents the difference between the dry-bulb temperature and the wet-bulb temperature, indicating the maximum potential cooling that can be achieved through evaporation.
How do you calculate capacity of cooling tower in terms of tonne?
calculation on mass flow rate, wet bulb temp, approach, range & condition of cooling tower installation.
Explain how you would use a wet bulb thermometer and a dry bulb thermometer to find the relative humidity?
the wet bulb is cooler
What does a wet bulb and a dry bulb measure?
A wet bulb measures the temperature after water evaporation allows to cool and a dry bulb measures air temperature.
