A Method to Determine the Slip Factor of Centrifugal Pumps through Experiment

摘要

In this paper, a method to determine the slip factor of centrifugal impellers is proposed based on the experimental result of the external performance of centrifugal pumps. This proposed method is superior to the conventional experimental method, which needs not to measure the flow parameters at impeller outlet. The results show that the present method can be used to obtain the slip factor at off-design condition in a wide range of flow rate besides at the design point.
