WebApr 8, 2024 · The method of finding the air density is quite simple. You have to divide the pressure exerted by the air into two partial pressures: of the dry air and of the water vapor. Combining these two values gives you the desired parameter. Calculate the saturation vapor pressure at given temperature. T.
