Unformatted text preview: The velocity is 0.9 m/s. a. What is the minimum allowable gate opening for the upstream flow to be possible as specified? b. If the gate opening is instantaneously set to 0.15 meters: i. What is the initial unit discharge, q , under the gate? ii. What is the final depth at the upstream side of the gate. Problem #4: Water is flowing at a velocity of 2.6 ft/s and a depth of 1.1 feet in a rectangular channel. a. The flow encounters a smooth upward step of 0.2 feet. i. What is the depth of flow on the step? ii. What is the absolute change in water level compared to the channel bottom before the step? iii. What are the Froude numbers upstream and at the step? b. Find the maximum allowable size of upward step for the upstream flow to be possible as specified....
