Hydrodynamic forces on reverse tainter valves ; hydraulic model investigation

Abstract : This technical note presents laboratory data of loads on vertical-frame and double-skin-plate valve designs. The objective is to identify differences in hoist forces for these two reverse tainter valve designs. A physical model was instrumented with a load cell to measure valve hoist loads. Comparison is made between the hoist forces acting on a vertical-frame and a double-skin-plate valve given the same head and discharge.
