Duct Air Velocity (FPM & m/s)
Calculate airflow velocity inside round and rectangular ducts. Classify acoustic noise and static friction penalties.
Technical Engineering Guide & Field Diagnostic Practices
Air velocity directly governs sound levels, static pressure drops, and diffuser throw distance. Keeping air velocities below 800 FPM in residential living quarters prevents unwanted fan and grill rumble.
