Select the duct material from the drop-down list (most duct sizing tools are typically based on galvanised steel ducting by default) Enter the air flowrate in litres/second (can change to cubic metres/second by use of drop-down to the right of the input).
- This online air duct calculator is used to calculate the velocity of air flow feet per minute (FPM), and feet per second (FPS) through any shaped (circle, square or rectangle) ductulator with either diameter, sides or area. Code to add this calci to your website.
- Duct Sizer (Ductulator) for HVAC air ducts. It is designed for calculating and sizing duct dimensions according to air volume CFM, roughness, velocity, etc. It is available in SI and British IP units. Duct sizing needs a ductulator or software but this excel calculator performs the same calculations.
Air duct also termed as ductulator is a passage that is used to provide fresh air into rooms, buildings etc., Air ducts may be in circular, square and in rectangular shapes. This online air duct calculator is used to calculate the velocity of air flow feet per minute (FPM), and feet per second (FPS) through any shaped (circle, square or rectangle) ductulator with either diameter, sides or area.
Air Duct Velocity Calculator
Air duct also termed as ductulator is a passage that is used to provide fresh air into rooms, buildings etc., Air ducts may be in circular, square and in rectangular shapes. This online air duct calculator is used to calculate the velocity of air flow feet per minute (FPM), and feet per second (FPS) through any shaped (circle, square or rectangle) ductulator with either diameter, sides or area.
Formula:
Ductulator Velocity = ( 576 * Air Flow in CFM ) / (3.14 * Diameter2)When diameter is given Ductulator Velocity = ( 576 * a ) / ( Side1 * Side2 * 4) When sides are givenDuctulator Velocity = Air Flow in CFM / Cross Sectional AreaWhen Area is givenExample
The velocity of an air duct with area 16 sq.ft and air flow of 10 CFM would be :
V = 10 / 16 = 0.625 FPM
When converted to FPS, it is 0.0104 FPS
