How do i find relative humidity
WebIt can be expressed. relative humidity (in %) = e / es × 100 (Equation 1) Unfortunately, there is no simple, direct formula for converting between dew point and relative humidity. Conversions between these two parameters must be carried out via the intermediate step of evaluating both the actual vapour pressure of water and the saturation ... WebApparently this relationship is fairly accurate for relative humidity values above 50%. More details can be found in the article: Lawrence, Mark G., 2005: The relationship between relative humidity and the dewpoint temperature in moist air: A simple conversion and applications. Bull.

WebThen, subtract the temperature of the wet bulb from the temperature of the dry bulb to find the humidity percentage. If the dry bulb is 26 degrees C and the wet bulb is 15 degrees C, for instance, you would subtract the latter value from the first and come up with a “depression” of 11 degrees C. Record this depression value also.
