A duct size calculator, commonly known as a ductulator, depends on factors like the size of the space you’re heating or cooling, air flow velocity, friction loss, and available static pressure of the HVAC system.
Ductulate HD provides a quick and simple way to calculate any combination of air volume, pressure loss, velocity and duct size (rectangular or round). Imperial units: - Air Volume, CFM, - Velocity, FPM - Pressure Loss, Inches of H2O - Dimensions, Inches Metric units: - Air Volume, L/s...
Watch out: there is no one right answer to "how long can I make my bath exhaust vent duct run?" is that ... it depends on The fan model (its size and CFM rating) or the required or "design" flow rate in CFM (from your local code, such as 60 or 80 CFM). Watch out: Indust...
The chart below can be used to estimate velocities in air ducts. The default values are for air flow 400 cfm (680 m3 /h) , duct size 8 in (200 mm) and velocity 1150 fpm (5.8 m/s) . Download and print Air Ducts - Velocity Diagram! Air Ducts Friction Loss make 3D HVAC models...
