5.13 Range of pump operation
When sizing and selecting centrifugal pumps for a given application, the pump efficiency
at design should be taken into consideration. The pump characteristics indicate the point
of BEP and its variation with respect to the flow rate Q.
This is an important factor; however, it is almost improbable that the pum ...
