Enthalpy of Humid Air Kj/Kg

Psychrometric charts are made of defined equations extracted from humid air properties. You can calculate the enthalpy of humid air if you have the mixing ratio which represents the ratio of mass of water vapour with respect to the mass of dry air and the air temperature. To calculate the mixing ratio we need the water vapour pressure.
