Q1) Consider a rectangular channel with a constant width b, a) Obtain the equation of water surface profile (dy/dx) as function of Froude number and channel bottom slope in a channel transition assuming that over a short distance Ax, the energy losses can be neglected. b) Using the equation you have obtained, draw the water surface profile if flow is supercritical and if there is a downward step at the channel bed and show your results on the graph of...
The channel transports water at 6 m3/s. The depth of flow is y = 1.5 m
The channel transports water at 6 m3/s. The depth of flow is y = 1.5 m. Suppose that d = 3.5 m. (Figure 1) Water flows in a rectangular channel with a velocity of 4 m/s and depth of 2.9 m. Part A What other possible speed of flow provides the same specific energy for the same volumetric flow? Part C Determine the specific energy of the flow. Part D Determine the minimum specific energy of the flow.

A trapezoidal channel has a side slope of 1:1 and a bed width of 6.0 m. A hydraulic jump with a height of 0.5 m (i.e. the difference between water surface elevation upstream and downstream of the jump) is encountered in the channel. If the channel has a discharge of 10 m3/s, determine the critical depth in the channel. Plot the momentum curve and determine the flow depth immediately upstream and downstream of the jump.

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...

Q2) A canal of trapezoidal section has bed width of 8 m and bed slope of 1 in 4000. If the depth of flow is 2.4 m and side slopes of the chamel are 1 horizontal to 3 vertical, determine the average flow velocity and the discharge carried by the channel. Also compute the average shear stress at the channel boundary. Take value of Chezy's constant = 55. Q3) 6.11. A power canal of trapezoidal section has to be excavated...

Specific discharge of a wide rectangular channel is 10.0m2/s (Q 10.0m3/s/m). The channel consists of two long reaches having the following bed slope, So1 -0.0001 (for ABC), and So2 = 0.008 for (CDE), (see Figure 1) respectively. There are two gates to control the flow and the flow depth at the vena contractor after each gate is approximately 0.3m. Take the Manning's coefficient as 0.015 Locate every possible flow changing locations and, sketch and name the water surface 1. profiles...

A pump delivers water at 50Cbetween reservoirs differing in elevation by 30[m]. The 0.25[m]diameter commercial steel pipe between the reservoirs is 800[m] in total length with a dis-charge side length of 712[m]. Total minor losses for the system contribute a k coefficient equal to 8. The pump characteristic curve is represented by the equation (in SI units): HP= 35.5 + 165Q−4820Q^2. 1. Compute the match point for the system (operating head and discharge). Provide a graph clearly indicating the match...
