The flow rate depends on the width at the outlet of the impeller, while the pressure depends on the diameter of the impeller. This is the most fundamental characteristic of centrifugal pumps.
The flow rate depends on the width at the outlet of the impeller, while the pressure depends on the diameter of the impeller.
Flow rate is also related to rotational speed and impeller width, while head is related to the impeller diameter and suction lift
So that is the flow rate of the centrifugal pump; the head is only related to the pump itself and not to the piping system?
