With our Air Flow calculator, it is possible to:
To use this calculator, type in the values and it will automatically show the results below.
Our Air Flow Conversion tool is also available, should you need to convert common units of air velocity.
Air Flow Equations for working out the velocity of air coming through a hose or tube and the pressure loss of the air going through these.
Velocity of Air in Feet per Second = √(25,000 * Loss of Pressure in Ounces per Square Inch * Inside Diameter of the Pipe in Inches) / Length of Pipe in Feet
Loss of Pressure in Ounces per Square Inch = (Length of Pipe in Feet * Velocity of Air in Feet per Second2) / 25,000 * Inside Diameter of the Pipe in Inches
