Psychometric Equation Question
(OP)
Is there an equation that could be plugged into an excel spreadsheet to calculate enthalpy at a known dry bulb and wet bulb temperature? Or is there a equation for total energy with known entering and leaving dry bulb/wet bulb air temperatures?

It works great and gives you many other properties if needed.

Can you provide a link please, I couldn't find it with google.
Thanks

H = (0.24 x T) + [W x (1061 + 0.444 x T)]
Where:
H = enthalpy (Btu/lb)
T = dry-bulb temperature (°F)
W = specific humidity (lbwater / lbdry air)

Making your own spreadsheet is pretty easy if you refer to ASHRAE HOF equations, provided you know DBT and WBT. The real trouble is with DBT and RH.
