Centrifugal and Axial Flow Pump Affinity Laws:

Speed changes & impeller diameter remains the same:

Q1/Q2 = N1/N2

H1/H2 = (N1/N2)²

P1/P2 = (N1/N2)³

Impeller diameter changes and speed remains the same:

Q1/Q2 = D1/D2

H1/H2 = (D1/D2)²

P1/P2 = (D1/D2)³

BASIC FORMULAS Q = Flow(m³/h)H= Head(m) Density = SGEff = Pump Eff%
