What is "Free Area"

(See also "effective area"). What is "Effective Area"
• Effective area is the net area (in square feet) of a grille utilized by the area stream in passing through the face openings.

It is used in the equation: CFM= Face Velocity X Effective Area. This is the basis for most engineering data.
