It also asks for the hydraulic efficiencies for each of the flow points and, in return, prints the HP required as "data lables" on each of the frequency curves. . This short publication is a guide to the proper selection, installation, and start up of new and replacement centrifugal pump motors. . In "Centrifugal Farce Affinity" we took a look at the affinity laws and showed how the predict pump performance when its speed changes or its impeller is trimmed. .
