Page 11: Appendix C - Airflow Volume Calculations
APPENDIX C - AIRFLOW VOLUME CALCULATIONS To calculate cubic feet per minute (CFM) from a measured air velocity (FPM), you need the calculated cross-sectional area of the air f ow stream: Volume Flow (CFM) = Velocity (FPM) X Area (sq ft). In a rectangular duct this cross sectional area equals the Width times the Height. -
