Tests of a wicket-gate pump-turbine model at the Newport News hydraulic laboratory and at the California Institute of Technology are described in this paper. The model was one of a series used in a study of pumps suitable for Grand Coulee. Characteristic curves both as a pump and turbine are illustrated, and expected-performance curves for a prototype stepped up to Grand Coulee conditions are developed from the tests. In conclusion, a summary is given of the advantages of the wicket-gate pump-turbine. |
