Air Mixture Temp Formula (CFM or Air 1 x Temp of Air 1) + (CFM or Air 2 x Temp of Air 2) Total CFM % of Outdoor Air = Mixture temp – Return Air Temp Outdoor Temp – Return Air Temp. Latent Heat Formula= 0.68 x CFM x Delta Grains/Lb = BTU h Total Heat Formula= 4.5 x CFM x Delta BTU/lb (Enthalpy) Sensible Heat Formula= 1.08 x CFM x Temp D= BTU h
