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.


Which one is always higher wet bulb temperature or dry bulb temperature?

The wet bulb temperature is always lower than the dry bulb temperature. The wet bulb temperature is the temperature taken by a thermometer covered in a wet cloth and exposed to moving air, and it reflects the evaporative cooling effect.


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.

No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

What cause the wet bulb thermometer to read lower than the dry bulb thermometer?

because the water causes the temperature to be lower


Why is the wetbulb thermometer read lower than The dry bulb thermometer?

The wet bulb thermometer is typically read lower than the dry bulb thermometer because the evaporation of water on the wet bulb cools the sensor by removing heat from it. This process is known as evaporative cooling and results in a lower temperature reading on the wet bulb thermometer compared to the dry bulb thermometer.


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.


What would the dew point temperature be when the wet and dry bulb temperature are the same?

the "current" temperature, ie, the temperature at which wet bulb and dry bulb are the same. when the wet bulb and dry bulb temperaturs equalized the dew point emperature equals them, because the air is saturated now.


What cause wet bulb to read lower than dry bulb?

Evaporation of the water in the wet bulb fabric cover causes the temperature of the wet bulb to go down. When the air is dry, more water will evaporate, and when the air is saturated, less will evaporate.


What would happen if a wet bulb had the same temperature as a dry bulb?

If the wet bulb temperature is the same as the dry bulb temperature, it means that the air is saturated with moisture and the relative humidity is at 100%. This indicates that the air is at the dew point temperature, and condensation may occur.


How does the difference between the dry bulb temperature and the wet bulb temperature to the relative humidity?

The larger the difference between the dry bulb temperature and the wet bulb temperature, the drier the air, indicating lower relative humidity. Conversely, a smaller difference between the two temperatures suggests higher relative humidity in the air. This relationship is fundamental to psychrometry, which is the study of air and its properties.
