Moist Air - Degree of Saturation

Sponsored Links

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)
