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 / xs (1)
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)
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)
- Moist and humid air - psychrometric charts, Mollier diagrams, air-condition temperatures and absolute and relative humidity and moisture content.
- Relative humidity in moist air can estimated by measuring the dry and wet bulb temperature.
- The mass of water vapor present in moist air - to the mass of dry air.
- Maximum water content in humid air vs. temperature.
- The moisture holding capacity of air increases with temperature.
- Saturation pressure and maximum water content in compressed air.
- Dry Bulb, Wet Bulb and Dew Point temperatures can be used to determine the state of humid air.
- Pressure, temperature and volume in a perfect ideal gas like moist air (air with water vapor).
- The pressure in a mixture of dry air and water vapor - humid or moist air - can be estimated by using Daltons Law of partial pressures.
- Density of the mix of dry air and water vapor - moist humid air.
- Sensible and latent heat of moist air.
- Psychrometric table with humid air properties like saturation pressure, specific volume, enthalpy and entropy.
- Relative humidity in moist air is the ratio of partial vapor pressure to air pressure.
- Saturation pressure of water vapor in moist air vs. temperature.
- Online calculator, figures and tables with water saturation (vapor) pressure at temperatures ranging 0 to 370 °C (32 to 700°F) - in Imperial and SI Units.
