1 - Electric heat - temperature rise method:
CFM = BTU's / (ΔT x 1.08)
Input: Temp. rise(°F) ΔT , Volts & Amps
Enter any two parameters to get the third:
CFM = BTU's / (ΔT x 1.08)
Input: Temp. rise(°F) ΔT , Volts & Amps
Enter any two parameters to get the third:
2 - Velocity method:
Input square inches of duct & ft. per minute
formula: CFM = (Velocity in ft. per min.) x (area in sq. ft.)
