The concept of air velocity can be used various ways in applications such as HVAC (Heating, Ventilation & Air Conditioning) as well as for pneumatic / air-powered tools & equipment.

Air velocity (which can be explained as distance traveled per unit of time) is usually expressed in LFM (Linear Feet per Minute). By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing at a specific time. While volume flow is usually measured in CFM (Cubic Feet per Minute).

Enter the values, select the units and click “calculate” and the results will appear.
