Download or read book Characteristic Pressure Distribution in Conduit Inlets of Earth Dam Flood Control Outlet Works written by Yen-Hsi Chu and published by . This book was released on 1969 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes a study of entrance pressure measured in nine hydraulic models and two laboratory investigations of entrance designs for earth dam flood control outlet works. The experimental data are examined to determine the effects of upstream face geometry, guide piers, and bulkhead and gate slots. Both the two-dimensional and three-dimensional type inlets are considered and compared with idealized inlets. The results are presented graphically in terms of dimensionless pressure drop coefficients for use in estimating pressure conditions to be expected in design practice. Design criteria are recommended.
