Water flows at 11 m3/s in a rectangular channel of width 5 m. The slope of the channel is 0.001 and the Manning roughness coefficient is equal to 0.035. If the depth of flow at a selected section is 2 m, calculate the upstream depth at 500 m from the selected section using the standard step method
02) A long rectangular channel is 3 m wide with Manning roughness of 0.018 and bottom slope of 2%. The channel runs downstream from a reservoir into a free overfall at its end. In the reservoir the water surface level is 1.35 m above the bed of the channel at the entrance. Ignore local loss at entrance. a) Calculate the critical depth, the discharge and the normal depth of the channel. (5/8) b) Sketch the water surface profile in the...

9) A rectangular channel 8 feet wide carries 2.5 ft/s of water at a depth of 3.2 feet. a) What are the most efficient attributes (d, A, P, and R) of the channel? b) If a 1-foot wide pier is placed in the middle of the channel, find the elevation of the water surface at the pier. What is the minimum width of the constriction that will not cause a rise in the upstream water surface?

chanud! Par ritengaalr Alternative a for rectes gual 25 pts) A rectangular channel is 3.50 m wide conveys a discharge of 14.0 m/s at a depth of 2.0 m. It is proposed to reduce the width of the channel at a hydraulic structure. Assuming the transition to be horizontal and the flow to be frictionless determine the water surface elevations upstream and downstream of the constriction when the constricted width is: (a) 3 m. (Plot the specific energy versus depth...
please show all the steps thank you 2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...
A 1.7 m wide, 4000 m long rectangular channel carries 1.6 m/s of water. The depth of the flow is 0.9 m. The channel is constructed from rough-formed concrete with a roughness coefficient of n-0.015. What is the difference in elevation between the two ends of the channel?
water flows at a rate of 20 m3/s through a rectangular channel 4.0 m wide from a "steep slope" to a 'mild slope", creating a hydraulic jump. The upstream depth of flow is 1.20 m Find the following: (a) the downstream depth of flow, (b) the energy loss in the jump, anid (c) the upstream and downstream velocities 2)
A 12-ft-wide rectangular channel conveys 3,030 cfs. Determine the normal and critical depths for the concrete channel (1% slope). Also determine the flow classification (critical, supercritical, or subcritical) when the channel flows at normal depth.
