Moist Air - Degree of Saturation
Humidity ratio of moist air to humidity ratio of saturated moist air.
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 / x s (1)
where
μ = degree of saturation
x = humidity ratio of the air (kg h20 /kg dry_air )
x s = humidity ratio of the air at saturation at the same temperature and pressure (kg h20 /kg dry_air )
The degree of saturation can also be expressed as:
μ = φ (p a - p ws ) / (p a - p w ) (2)
where
μ = degree of saturation
φ = relative humidity (%)
p w = vapor pressure (mbar)
p ws = saturation vapor pressure at the actual dry bulb temperature (mbar)
p a = atmospheric pressure of moist air (mbar)
