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 else can I help you with?
What is the wet bulb depression if the dry bulb is 20 and the wet bulb is 17?
15
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 is the use of dry and wet bulb tenperature?
How you would use a wet-bulb thermoter and a dry-bulb theremometer to fine the relative humidity?
If the difference between a wet bulb and a dry bulb thermometer is great is the humidity low?
No, the humidity is high when wet and dry bulb temps are far apart.
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.
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.
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.
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.
What instrument do you use to measure dry bulb and wet bulb temperature?
You would use a sling psychrometer to measure both dry bulb and wet bulb temperature. The dry bulb thermometer measures the air temperature, while the wet bulb thermometer measures the temperature with evaporative cooling considered.
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.
What thermometer has a wet and dry bulb?
psychrometer
