NOTE:
The fixed area of the fume hood is an area that remains open
regardless of sash position or movement. For example, most fume hoods
have an intake gap under the lower airfoil and above the cabinet of the fume
hood (typically a 1 inch gap). Also include 1% of the maximum open face area
in this calculation for other open areas, such as the space between the sash
and the track, and leakage.
