1) Item 1 (Stall 2 to Stall 9)
1) For Island Hood, QE = 1.4 v x 2 (L + W ) H 2) For Wall Mounted Hood, QE = 1.4 v x (P) x H
Fan Selection, Type = Bifurcated Aerofoil Cap = 32000CmH, 50mm WG
Where, QE = V = L = W = P = H =
Exhaust flow rate in m3/hr (CMH) Captured velocity in 1080 m/hr (0.3m/s) Length of hood in m Width of hood in m Perimeter of exposed hood in m Height of emitting surface to hood level in m
*Supply air flow rate is based on 80% to 90% of Exhaust rate.
