Enthalpy of wet air is the enthalpy of an air/vapour mixture.
Enthalpy of wet air is given by:
H=Ha+Hv
m*h=ma*ha+mv*hv --------> h=ha+w*hv
where
h: Enthalpy of wet air (kj/kg dry air)
hv: enthalpy of vapour
ha: enthalpy ofair
ma: mass of air
mv: mass of vapour
w: specific humidity
As for humid heat, I have to admit I didn't have a clue what that is. But i googled it and this is what came up: http://en.wiktionary...wiki/humid_heat
Apparently it's the specific heat (Cp) of an air/vapour mixture.
