The flow rate (Q) of a centrifugal pump is the useful volume flow delivered by the pump via its outlet cross-section (see Pump discharge nozzle). Volume flow rates which are tapped upstream of the pump's outlet cross-section for other purposes (e. g. bypass) must be taken into account when calculating the pump's flow rate. If the fluid handled is compressible, a conversion must …
