Define following terms: 1) specific humidity 2) absolute humidity 3) relative humidity 4) degree of saturation.
Specific humidity:- It is defined as the ratio of mass of vapour to the mass of dry air in a given sample of moist air. Specific humidity ma mv Absolute humidity:- It is defined as the actual mass of water vapour in unit volume of air. Its unit is gm/m3 Relative humidity:- It is defined as the ratio of partial pressure of water vapour in a given volume of mixture to the partial pressure of water vapour when same volume of mixture is saturated at the same temperature. Degree of saturation:- It is defined as the ratio of mass of water vapour associated with unit mass of dry air to the mass of water vapour associated with saturated unit mass of dry air at same temperature.
