You already know intuitively what humidity means: it's the amount of moisture in the air. But measuring humidity turns out to be a little more difficult than defining it. One way to measure humidity is with the aid ofa wet bulb thermometerand a dry bulb thermometer. The temperatures measured...
to measure relative humidity, it has to be used in conjunction with a dry bulb thermometer. The dry bulb temperature is basically the temperature of the air, but the wet bulb temperature is affected by the evaporation of water from the fabric enclosing the bulb. Evaporation is an endothermic ...
Dry Bulb (DB)- Shielded from direct sunlight - reads actual air temperature. Wet Bulb (WB)- With moistened wick over the bulb - will read varying temperatures depending on the rate of evaporation. Rate of evaporation varies with the humidity level. ...

The wet bulb calculator operates on a simple principle. You can use it to work out the wet bulb temperature from just two numbers: temperature and relative humidity. Keep reading if you want to discover some wet-bulb applications, what the military benefits of the Wet-Bulb Globe Temperature ...
Wet Bulb temperature can be measured by using a thermometer with the bulb wrapped in wet muslin. The adiabatic evaporation of water from the thermometer bulb and the cooling effect is indicated by a "wet bulb temperature" lower than the "dry bulb temperature" in the air. ...
