Witryna16 wrz 2024 · The impeller is the first component to investigate when assessing centrifugal pump efficiency. For any impeller, we know that its head varies as a square of the change in speed. By doubling the speed, the head will increase four times as much. The same applies to small changes in diameter if you keep the speed constant. WitrynaThe pump head increases with the square of the pump speed and impeller diameter. Flow is proportional to speed and impeller diameter. Head is proportional to (speed)2 …
