http://www.atmo.arizona.edu/students/courselinks/fall12/atmo336/lectures/sec1/humidity.html WebIn this example we know the relative humidity and the saturation mixing ratio and we will use the RH equation to first calculate the mixing ratio. Simply rearranging the RH equation, U = (RH) x (U s) = (0.5) x (7.6 g/kg) = 3.8 g/kg. Step 3. Use the table of saturation mixing ratios to find the dew point temperature. fht magazineWebActual Vapour Density/Saturation Vapour Density x 100. The actual vapour density calculates the current water vapour (g/m 3) in a space. The saturation vapour density measures the maximum amount of moisture that the air can hold at that temperature (g/m 3 ).
