Abstract

"A closed conduit, such as an overflow pipe for a conservation pond or a sanitary lagoon, will not flow full if laid on a slope that is hydraulically steep unless the pipe entrance receives special attention. A steep conduit slope is necessary to insure that the pipe entrance controls flow.

The recently introduced hood inlet will permit the closed conduit to flow full, even if on a hydraulically steep slope, upon a slight submergence of the inlet crown. The hood inlet is formed by cutting the pipe at an angle so that the crown of the inlet projects beyond the invert.

In this study, optimum hood length and entrance loss coefficients are determined for the hood inlet. The effects on pipe flow of conduit slope and vortex action are presented. As a further development of the hood inlet, initial investigations are made on a surface flow excluder for use as an overflow structure for sanitary lagoons"--Abstract, page 2.
