11.3 CALCULATING AIRFLOW CFM
• The formula for calculating airflow using temperature rise and heating BTUH for units
with electric resistance heat is:
H
eating BTUH
CFM =
1.08 x Temp. Rise
11.4 CALCULATING CORRECTION FACTOR
• For correction of electric heat output (kW or BTUH) or temperature rise at voltages
other than rated voltage multiply by the following correction factor:
Applied Voltage
2
Correction Factor =
Rated Voltage
2
