Abstract

Usually, when examining the outflow pattern under a gate in a pressure conduit [1,2], the pressure distribution below the gate is assumed to follow the hydrostatic law.However, as the jet flows out from under the gate, it curves, inevitably generating centrifugal forces that press the transit flow toward the bottom. As a result, the pressure distribution in this area deviates from the hydrostatic one. Some authors [3,4] noted this phenomenon, but their studies were conducted for free-surface flow.
