Abstract:	In order to predict the performance of mixed-flow pumps over the whole flow-rate range, it is necessary to establish a calculation method of theoretical head and water power loss caused by a reverse flow at the inlet and the outlet of an impeller. In this report, a reverse flow model at the impeller inlet is proposed together with a slip factor formula, and a prediction of theoretical head and water power of mixed-flow pumps is presented by a simple one-dimensional calculation using this inlet flow model. The results show that the present method gives a good estimation for the inlet velocity distributions and for the theoretical head and water power in the whole flow-rate range.
