Air - Absolute Humidity

Absolute humidity is the actual mass of water vapor present in the air water vapor mixture.

Humidity is the quantity of water vapor present in air. It can be expressed as absolute, specific or a relative values.

Absolute humidity is the actual mass of water vapor - m_h20 - present in the air water vapor mixture.

In SI-units the absolute humidity may be expressed in kilograms of water vapor (kg/m³, g/m³)
In imperial units the absolute humidity may be expressed in lbs of water vapor (lbs/ft³, gr/ft³)

Air can be humidified by adding water or steam.

Estimate the amount of steam required (lb/h in 100 cfm) in humid air.

Using steam to humidify air.

The mass of water vapor present in moist air - to the mass of dry air.

The optimum relative humidity ranges for bacteria, viruses, fungi, mites, asthma.

Cooling and dehumidifying processes of moist and humid air - sensible and latent cooling.
