Equivalent temperature

The equivalent temperature is the temperature of the air, which is reached when the total condensed water vapor contained in it and if it uses the heat released energy to increase the air temperature.

It can be calculated via

With

Lv = specific heat of vaporization of water. This value is dependent on temperature and at 25 ° C for about 2.5 x 106 J / kg

Cp = specific isobaric heat capacity of dry air, 1005 J / ( kg K)

X = mixing ratio; Mass fraction of water in relation to the mass of dry air ( use here in g / kg)
