Duct Velocity Calculator: Air Velocity = Airflow / Duct Area

In HVAC, it’s sometimes useful to calculate the velocity of air in the ducts. All central air conditioners, for example, require ductwork with the specified size of ducts and airflow (measured in CFM). To calculate the speed of air in the ducts, we use a duct velocity calculation (you can find the calculator below). Let’s … Read more
