CAPACITY-GALLONS PER MINUTE (at bep)
Figure 3-57. Viscosity performance correction chart for small centrifugal pumps with capacity at best efficiency point of less than 100 GPM
(water performance). Note: Do not extrapolate. For small centrifugal pumps only, not for axial or mixed flow. NPSH must be adequate. For
Newtonian fluids only. For multistage pumps, use head per stage. (By permission, Hydraulic Institute Standards for Centrifugal, Rotary, and
