WebRelative humidity (RH) = Water Vapor Pressure (P) / Saturated Water Vapor Pressure (P 0) RH = P/P0 Saturated Water Vapor Pressure (P 0) depends on the temperature. Two states State 1 Actual water vapor pressure at beginning = P 1 RH = 80% Saturated water vapor pressure at beginning = P 10 = 12.171 kPa State 2 WebTo calculate the relative humidity, you need to know the temperature and the dew point. The formula for relative humidity is: Relative Humidity = (Actual Vapor Pressure / Saturation Vapor Pressure) x 100%. For example, if the temperature is 80°F and the dew point is 60°F, the actual vapor pressure is 14.7 psi, and the saturation vapor ...
