Simply understand standing wet bulb Temperature and Dew and Relative humidity?

Wet bulb temperature: It is the temperature of the atmospheric air measured with a thermometer whose bulb is wrapped in a spongy component and moistened with water that allows normal evaporation.

Atmospheric dew point: It is the temperature at which the water vapor contained in the atmospheric air begins to condense.

To get an idea of ​​the amount of water vapor in the atmospheric air at given conditions, the partial pressure of the water vapor is related in percentage terms to those conditions with the partial pressure of the saturated water vapor.

The equipment to measure the relative humidity is the Psychrometer, which consists of 2 thermometers to measure the temperature of the dry bulb and the wet bulb of an air streams at a speed between 4 and 10 m / s.
