Mean Coincident WBT are the average of the indicated WBT occurring concurrently with the corresponding dry bulb temperature (DBT). Hope this clarifies the point. Rahul
for air water system wet bulb equals to dry bulb at 100 % relative humidity for that given temperature of air.
wet-buld depression
That means that there is 100% humidity. Normally evaporation from the wet bulb keeps its temperature lower than the dry bulb. At 100% humidity, there would be no evaporation, so they would show the same temperature.
You use a Hygrometer.
-17
the evaporation off the moisture on the wet bulb absorbs the heat.
100% RH
wet bulb temparature will increases

A wet bulb measures the temperature after water evaporation allows to cool and a dry bulb measures air temperature.
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.
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.
it is difference between wet bulb temperature and dry bulb temperature.
wet-buld depression
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
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".
