The relative humidity of the air at the dew point temperature is 1 and its enthalpy is lower than that of the same air at its dry bulb temperature and wet bulb temperature. Air absolute humidity (y) is the ratio of the amount of water vapour (mv) to the amount of dry air (ma). Usually it is expressed in kg of water vapour per kg of dry air.
