2. Calculate nominal step between holes and hole position deviation form nominal
1. Verification of project constraints and determination of aspirator speed
3. Determination of necessary Sensitivity Level
and the hole diameters
S1 = L1 / ( Number of holes – 1 ) = 35 / 5 = 7 m (≥2.5m)
± 0.2*7m = ±1.4m
