Abstract
A thorough and detailed analysis of flow-line losses was computed from data obtained by tests on the unusually long flow line leading to the hydroelectric generating plant at Chelan, Wash. This paper contains the results of that analysis, and includes:
(1) The losses that occur in each part of the flow line;
(2) The coefficients of roughness that are applicable to the large concrete and steel lined pipes of this installation;
(3) An unusual and complete analysis of the losses that occurred in the wye-branch; and
(4) A segregation of the diversion losses (see heading, “Definitions of Symbols”) in the wye-branch and lower penstock bends from the losses due to frictional resistance, as a means of checking laboratory tests and research work that was being conducted along this line.
The tests were made and a report was prepared as a means of facilitating the most economical operation of the generating station and to supply additional data in the furtherance of engineering knowledge and its application to future designs involving these features.
