Is the wet bulb thermometer reading always higher than a dry bulb reading?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
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.

Why do doctors advice to put wet cloth on our forehead when we have a high fever?
The evaporation of water from the cloth lowers the temperature of the cloth and thus hopefully by conduction the temperature of the person. Note that this method does not work in spaces with 100 % relative humidity.
Why do doctors advice to put strips of wet cloth on the forehead of a person having high temperature.?
The evaporation of water from the cloth lowers the temperature of the cloth and thus hopefully by conduction the temperature of the person. Note that this method does not work in spaces with 100 % relative humidity.
Does the wet bulb thermometer on a WBGT have to be wetted with distilled water?
Yes, the wet bulb on a Wet Bulb Globe Temperature (WBGT) device should be wetted with distilled water to ensure accurate readings. Using distilled water helps prevent any impurities that may affect the measurement. It ensures the wet bulb accurately reflects the evaporative cooling effect.
Why does wrapping cotton wool around a thermometer cause the temperature to drop?
Wrapping cotton wool around a thermometer can cause the temperature reading to drop because cotton wool is a good insulator. It prevents heat from reaching the thermometer, resulting in a lower temperature reading.
What is the relative humidity if at 3 pm a dry-bulb thermometer reading is 66 degrees F and the wet-bulb reading is 66 degrees F?
The relative humidity is 100% because the dry-bulb temperature and wet-bulb temperature are the same, indicating that the air is saturated with moisture and cannot hold any more water vapor.
Why is the wet bulb reading necessary when checking the systems charge?
Why is the wet-bulb reading necessary when checking the charge
Outside temp gauge is wrong buick regal?
If the outside temperature gauge is not reading the right temperature on a Buick Regal, perhaps it has become damaged. It can also not read the right temperature if it is wet or covered with dirt or snow.
How does the difference between the dry bulb temperature and the wet bulb temperature to the relative humidity?
When the humidity in the surrounding air is low, the water in the wet cloth wrapped around the bulb of the "wet bulb" thermometer evaporates quicker, giving lower reading on that thermoneter, thus widening the gap between the wet bulb and dry bulb temperatures. The lower the humidity in the air, the quicker the evaporation, the lower the "wet bulb temperature".
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.
