SIGNIFICANCE OF BEP
Updated: Oct 20, 2021
1) BEP as a measure of optimum energy conversion
When sizing and selecting centrifugal pumps for a given application the pump efficiency at design should be taken into consideration. The efficiency of centrifugal pumps is stated as a percentage and represents a unit of measure describing the change of centrifugal force (expressed as the velocity of the fluid) into pressure energy. The BEP is the area on the curve where the change of velocity energy into pressure energy at a given flow rate; in essence, the point where the pump is most efficient.
