摘要：
The paper presents a basis for teaching centrifugal pump characteristics in an undergraduate course in turbomachinery. It is shown how the shock and frictional loss coefficients, key factors in the determination of pump characteristics, can be appropriately obtained. The first coefficient is obtained from the difference between the drag at a reference incidence and that at zero incidence, while the second is obtained from correlations for frictional loss in a spiral. The coefficients so obtained were used to obtain the real characteristics of a centrifugal pump impeller. © 2005 SAGE Publications.
