Abstract: Walker and Goulas have suggested that the Hydraulic Institute Chart, primarily meant for centrifugal pump 
performance prediction for Newtonian materials with a known viscosity, be extended to non-Newtonian 
slurries. The performance correction must make use of an apparent viscosity calculated at a shear rate of 2 
(  being the impeller angular speed) for low flow rates, and for high flow rates at a shear rate between 100-
1500 s-1. This is considered ambiguous. The present work calculates an apparent viscosity from a pump 
impeller average shear rate determined using the Metzner and Otto method and evaluates the accuracy of the 
Hydraulic Institute Chart in pump performance predictions for non-Newtonian materials.
