Here’s a neat cfm calculator that calculates cfm based on room area, ceiling height, and the. Web airflow (cfm) = room’s floor area × ceiling height (ft) × ach / 60 where: Volume flow is usually measured. When friction loss is lower, then a lower cfm will do the job. 85 cfm at 0.06 friction loss or 115 cfm with a 0.1 friction loss. Air velocity, or airflow, gets measured in cubic feet per minute (cfm) and is directly proportional to the size of ductwork.
