Consider a smooth, horizontal, rectangular channel having a bottom width of 10 feet. A sluice gate is used to regulate the flow in the channel. Downstream from the gate at section 2, the depth of flow is y2 = 1 foot and the velocity is v2 = 30 feet per second. Neglect energy losses under the gate. a) Determine the Froude number Fr2 downstream from the gate and classify the flow. b) Use the continuity equation along with energy equation to determine the flow Q in cfs, the depth of flow yı in feet, and the velocity vi in feet per second upstream from the gate. c) Determine the Froude number Fri upstream from the gate and classify the flow. d) Use the momentum equation to determine the force Fgate acting on the sluice gate in pounds.
