Relative humidity can also be expressed as the ratio of the vapor density of the air - to the saturation vapor density at the the actual dry bulb temperature. Relative humidity by density: φ = ρw / ρws 100% (2b) where φ = relative humidity [%] ρw = vapor density [kg/m3] ρ...
Specific humidity of moist air vs. relative humidity, water vapor and air density. Humidity is the quantity of water vapor present in air. It can be expressed as an absolute, specific or a relative value. If we know the relative humidity of the moist air and the water vapor density and ...
