Calculate Wet Bulb Temperature From Relative Humidity Formula

The following formula is used to calculate the wet bulb temperature.

Calculate wet bulb temperature from relative humidity formula. Calculate dewpoint wet bulb temperature from relative humidity. When the psychrometer is swung around by its attached chain or handle the air causes the water on the wick to evaporate which. Dewpoint and wet bulb from relative humidity. Bulletin of the am.

Determine the wet bulb and dewpoint temperature the given temperature is 40 deg c relative humidity is 50 and then actual station pressure is 3 millibars. A simple online weather calculator to find the dewpoint and the wet bulb temperature by knowing the values of relative humidity temperature and actual station pressure. In of mercury mm of mercury millibars hpa. Relative humidity and dewpoint from wet bulb.

Relative humidity is measured using a device called a sling psychrometer this consists of 2 side by side conventional thermometers one of which the wet bulb thermometer has a wetted wick placed at the bottom the other the dry bulb thermometer has no wetted wick. To calculate relative humidity in percent hereinafter denoted as rh from dry bulb temperature t and wet bulb temperature t w one can use a well known set of forward analytical psychrometric equations bohren and albrecht 1998. The relationship between relative humidity and the dew point temperature in moist air. Construction different materials react differently to different humidities so this temperature is needed when designing a building in different climates.
