WebCalculating relative humidity is an involved process that requires the measurement of dry, wet bulb temperatures & barometric pressure. You then have to do a series of calculations to find saturated vapour pressures, moisture content of air, enthalpies of water vapour & liquid water. One book that I used a long time ago was: – Fred WebHere are some formulas you can use: Equation 1: RH = E/Es × 100. In this equation, RH means relative humidity, E is the amount of water vapor, and Es refers to the amount of …

Air - Humidity Measurement from Dry and Wet Bulb Temperature

WebRelative humidity describes the amount of water vapor actually in the air (numerator), relative to the maximum amount of water the air can possibly hold for a given temperature (denominator). It is expressed as a percentage: R H = H 2 O a c t u a l H 2 O max This equation is not rendering properly due to an incompatible browser. See Technical ...
