Theoretical pump curve
WebbThe head developed by a pump is independent of liquid and a performance curve for water can be used for Newtonian liquids like gasoline, diesel or similar. Note that the required power to the pump depends on the liquid density and must be recalculated. NPSH and Liquids with Dissolved Gas WebbThe deviation between the theoretical and the experimental curve is 2-13% for the discharge between 19 m 3 /hr to 91m 3 /hr is indicated in Fig. 6. This deviation is due to …

Webb20 jan. 2012 · The overall efficiency of a centrifugal pump is simply the ratio of the water (output) power to the shaft (input) power and is illustrated by the equation below: Ef = PW / PS Where: E f = efficiency P w = the water power P s = the shaft power In the U.S., Ps is the power provided to the pump shaft in brake horsepower (BHP) and Pw is: WebbIn GB 50017-2003 [1], curve b was adopted to design the welded H-section columns fabricated from flame-cut plates buckling about two principle axes. It is found that curves H-7 are higher than curve b by 7.3% and 8.6% in average for buckling about y – y and x – x axes, respectively.

In fluid 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.
