The development of the methods of testing turbine models is described in this paper. The writer deals particularly with the more recent progress that has been made in determining cavitation characteristics. The interpretation of the laboratory results are important not only for designing the proper setting of the prototype to avoid cavitation, but also for predicting the power that can be expected. The application of the Moody formula for this purpose is discussed. Three outstanding methods used in the United States for measuring the quantity of water taken by even the largest hydraulic units can be depended upon for reliable results, and failure to make acceptance tests may retard progress materially in the design of future installations. In conclusion the collection of data by which the step-up formulas can be verified is emphasized as being of utmost importance.
