The dry bulb temperature is your average everyday straight-up temperature, the ones the weather reports discuss.
The wet bulb temperature is the temperature that would be reached if exposed water were allowed to evaporate into a parcel of air until it were saturated. It's not the dew point, which is just the temperature at which the current moisture content of the air would be saturated. It measures the resulting temperature after the air loses enough heat to evaporate water until it is saturated.
It is between the dry bulb and the dew point, and is useful for determining (among other things) how far the temperature might drop once precipitation starts (the precipitation will evaporate until the air is nearly saturated, using heat from the air to do so).
What else can I help you with?
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.
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.
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.
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 is atmospheric depression?
it is difference between wet bulb temperature and dry bulb 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.
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.
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.
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 is the relative humidity when the dry-bulb temperature is C and the wet bulb temperature is C?
50 percent
