What do I do when abrupt transition creates turbulence?

Airflow/TAB Impacts From InstallationV136 field-polished — distinct TAB/airflow answer

An abrupt transition can create turbulence, noise, and pressure loss. Verify the transition length/taper before locking it in.

Field checklist

This transition changes from [size] to [size] over [length]. Is this transition acceptable, or do you want a longer/approved fitting?

Do not make a short chopped transition because it is easier to fit.

Air does not like sudden shape changes. Abrupt transitions can cause turbulence, noise, and lower delivered air.
