WebApr 3, 2024 · The condition is called the best condition. Although the characteristic curves of various types of centrifugal pumps are different, they all have a common changing trend. (1) H-Q curve (flow-head curve) shows the relationship between pump head and flow. The pressure head of a centrifugal pump generally decreases as the flow rate increases. WebMay 22, 2024 · Pump Head – Performance Curve. In fluids dynamics the term pump head is used to measure the kinetic energy which a pump creates. Head is a measurement of the height of the incompressible fluid column the pump could create from the kinetic energy, that the pump gives to the liquid. The head and flow rate determine the performance of a …
