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. Witrynadimensionless form as the impeller flow rate number [1, 2] NQnD Q p p 3,(1) where n is the frequency of the impeller revolution and D is its diameter. Quantity N Q p does not depend on the Rey-nolds number of the impeller when this quantity exceeds ten thousand [1, 3, 6]. For impeller power input P the Power number has been …
