WebbThe gate is provided with a lifting mechanism so that the aperture beneath it may be set to any desired position. When closed, the aperture is sealed so that no flow can pass through the gate. In this experiment we measure the discharge under the gate and establish the effective coefficient of discharge.

WebbThe channel has a discharge of 200 cubic feet per second at a uniform flow (normal) depth of 2 ft. A sluice gate at the downstream end of the channel controls the flow depth just upstream of the gate to a depth z. Determine the depth z so that a hydraulic jump is formed just upstream of the gate. Webb30 sep. 2010 · The flow is shown to be mostly two-dimensional. Velocity fields were simulated using renormalization group k-epsilon and Reynolds stress model turbulence models, leading to an estimation of energy and momentum correction coefficients, head loss, and bed friction.
