RE: calculate cfm
1.08 x cfm x (T1-T2) = [m x Cp x (t1-t2)]/X
Where, T1 = inlet temp. of air in deg.F
T2 = outlet temp. of air in deg.F
m = mass of the substance you are heating in the dryer in lb
Cp = specific heat in btu/lb F
t1 = initial temp. of the substance in deg.F
t2 = final temp. in deg.F
X = drying time in hrs.
