Pump affinity
WebUsing affinity laws, the performance of a centrifugal pump can be accurately calculated for different speeds. Centrifugal Pump Power Calculator. This centrifugal pump power calculator is intended to calculate the mechanical power of a centrifugal pump at a set operating point. WebUsing the affinity laws, it is possible to determine approximate curves to estimate the centrifugal pump's new best efficiency point. Centrifugal pump affinity laws provide a method to determine a new pump operating point when a performance curve that indicates performance with different impeller diameters or operating speeds is not available.
