For example, air at sea level, and saturated with water vapor at 20 °c, has partial pressures of about 2.3 kpa of water, 78 kpa of nitrogen, 21 kpa of oxygen and 0.9 kpa of argon, totaling 102.2 kpa, making the basis for standard atmospheric pressure Figure 3.1 shows the saturation vapor pressure curve and the t d and t, e s Vapor pressure of liquid water and ice at different temperatures www.vaxasoftware.com table 2.

Temperature, the air is close to being saturated with water vapor. The top of this chart is the rh or relative humidity in your growing environment. For example, air at sea level, and saturated with water vapor at 20 °c, has partial pressures of about 2.3 kpa of water, 78 kpa of nitrogen, 21 kpa of oxygen and 0.9 kpa of argon, totaling 102.2 kpa, making the basis for standard atmospheric pressure Mass/mass ppm m(dry) ppm m = mwpw md (ptot −pw) 10 6 mw md =0.62199 (19) where pw = water vapour pressure ptot = total pressure mw = molecular mass of water md = molecular mass of dry air from wet air:
