Short 16 - Air Velocity is Useful
In this short podcast episode, Bryan covers how to measure air velocity directly at a return or supply and what those readings tell you.
Since many techs like to focus on CFM and static pressure readings, they can neglect air velocity in their measurements. Air velocity is the speed at which the air is moving. Conversely, static pressure is the force of the air against the sides of the ducts, and CFM is the air volume. We measure air mass in pounds (in the USA); when air is denser, you will have more pounds, but the volume will stay the same.
We primarily measure air velocity with a vane…
