Why does duct size directly control velocity? In this clip, Jonathan (co-founder at h2x) breaks down the simple formula that connects airflow, duct area, and velocity. The key insight: you want to size the smallest duct possible, but only if you can keep velocity within acceptable limits. The formula is straightforward: Velocity = Airflow Ă· Duct Area #hvacdesign #mechanicalengineering #ductwork #velocity #mechanicalengineer
