Degree of Saturation is the ratio of the humidity ratio of moist air - to the humidity ratio of saturated moist air at the same temperature and pressure.
The Degree of Saturation can be expressed as
μ = x / xs (1)
where
μ = degree of saturation
x = humidity ratio of the air (kgh20/kgdry_air)
xs = humidity ratio of the air at saturation at the same temperature and pressure (kgh20/kgdry_air)
The degree of saturation can also be expressed as:
μ = φ (pa - pws) / (pa - pw) (2)
where
μ = degree of saturation
φ = relative humidity (%)
pw = vapor pressure (mbar)
pws = saturation vapor pressure at the actual dry bulb temperature (mbar)
pa = atmospheric pressure of moist air (mbar)
