Abstract Based on the new theory of variety for researching a low head pump system,a new method to separate outlet conduit from pump system is put forward for measuring its hydraulic loss.Problems relative to the test device,losses calculation method and error analysis,etc.are illustrated.Compared with the traditional method,the new method has advantages of reducing expenses,shortening period and being much more accurate.The new method is applied to measure the hydraulic losses of two outlet conduits,the geometry shape of which are different.The test results signify that the hydraulic losses of outlet conduit are very sensitive to their geometry shapes.
