### Impeller Redesign & Pump Efficiency | Pumps &

2010-9-28 · efficiency of the pomp and the impeller . Hydraulic efficiency of the pump is determined by the formula th h H H η etah = = (6) Centrifugal pump is a flow machine, hence using the one-dimensional flow model to analyze the phenomena of energy conversion one can use fundamental Eulerian equation for Turbomachinery [11] [12]. Euler's equation takes the form
