WebMoist Air - Degree of Saturation - Humidity ratio of moist air to humidity ratio of saturated moist air. Moist Air - Enthalpy - Sensible and latent heat of moist air. Moist Air - Psychrometric Table for Pressure 29.92 inHg. - Dry … Specific humidity (or moisture content) is the ratio of the mass of water vapor to the total mass of the air parcel. Specific humidity is approximately equal to the mixing ratio , which is defined as the ratio of the mass of water vapor in an air parcel to the mass of dry air for the same parcel. See more Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, … See more A device used to measure humidity of air is called a psychrometer or hygrometer. A humidistat is a humidity-triggered switch, often used to control a dehumidifier. The humidity of an air and water vapor mixture is determined through the use of psychrometric … See more The relative humidity of an air–water system is dependent not only on the temperature but also on the absolute pressure of the system of interest. This dependence is demonstrated by considering the air–water system shown below. The system … See more At 100% relative humidity, air is saturated and at its dew point: the water vapor pressure would permit neither evaporation of nearby liquid … See more Absolute humidity Absolute humidity is the total mass of water vapor present in a given volume or mass of air. It does … See more Humidity depends on water vaporization and condensation, which, in turn, mainly depends on temperature. Therefore, when applying more pressure to a gas saturated with water, all components will initially decrease in volume approximately according to the … See more Climate control refers to the control of temperature and relative humidity in buildings, vehicles and other enclosed spaces for the purpose of providing for human comfort, … See more dr. hesse tierpharma gmbh co. kg
