Hood Flange Opening Flow Rate

Formula

  • \( Q = 0.75V(10x^2 + A) \)
Hood Flange 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)
