What Happens to Air Flow in Ducts When Size Changes

Air velocity in ducts is a really critical factor in how well ducts do their job of efficiently and quietly moving the right amount of air from one place to another. We'll explore that topic further in a future article but for now, let's nail down what happens to the velocity as air goes from a larger to a smaller duct.

Is there a way to calculate how large the return air

A non-filtered grill should be sized for a maximum face velocity of 500 FPM. Face velocity is how fast the air is going THROUGH the grill - i.e. the grill is not 100% open so a 24"x12" is 2 square feet of space BUT there is a grill covering a portion of that so you may have 1.3 square feet of actual open space.
