Hood Plain Opening Flow Rate

Rate of air exhausted from a plain multiple slot opening with 2 or more slots with an aspect ratio of 0.2 or greater

Formula

  • \( Q = V(10X^2 + A) \)
Hood Plain Opening Flow Rate - Air flowing through a plain opening.
Variable Units Description
V Speed: Foot Per Minute Required air capture velocity at x distance in front of the hood
x Distance: Foot Distance in front of the hood for required centerline capture velocity
A Area: Square Foot Area of the inlet openings (A = LW)
