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).
Concept of Air Velocity can be used various applications including all HVAC (Heating, Ventilation & Air Conditioning) as well as pneumatic / air-powered tools & equipment.
