• As to the formula predicting the efficiency of prototype water turbines by their model tests, many formulas have been already presented by many investigators and are used practically. It seems, however, these formulas are not always exact as to treatment of hydraulic pressure losses. In this paper the authors show the method predicting the efficiency of prototype water turbines using the model test data at different speeds. By this method more precise values of the efficiency can be obtained. A similar calculating method is applied to the test data using the different size models also.
