FAAST FLEX
Example:
E Exhaust pipe
T T-junction position
B1 Branch length
F First hole, Branch 1
PL Pipe length with low speed
with high aspirator speed
L1 Last hole position, Branch 1
N Number of holes
B2 Branch 2 length
L2 Last hole, Branch 2
4. For Branch 2, calculate nominal step between holes and hole position deviation from nominal
S2 = L2 / ( Number of holes – 1 ) = 23 / 5 = 4.6 m (≥2,5m)
± 0.2*4.6m = ±0.9m
5. For Branch 2, first hole position can be 5±0.9m
