Degree of saturation or percentage humidity: We have already discussed that the degree of saturation is the ratio of actual mass of water vapour in a unit mass of dry air to the mass of water vapour in the same … Continued
Psychrometric Relation: Specific humidity, humidity ratio or moisture content: It is the mass of water vapour present in 1 kg of dry air (in the air-vapour mixture) and is generally expressed in g/kg of dry air. It may also be … Continued
