Water flows at 4.3m/s in a rectangular channel of width 3 m and depth of flow 1m. If the channel width is decreased by 0.75m and the bottom of the channel is raised by 0.25m, Find the followings: The discharge per unit width before the constriction q m3/s/m Discharge per unit width at the constriction q" = m/s/m Water depth of flow in the constriction y2 =
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
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...
In a rectangular channel, water flows at a flow rate of 15 m3 / s. The width of the canal is 4.0 m and the water depth is 2.5 m. Without causing the water in the blast to swell: a) If the channel is narrowed without raising the channel base, what is the minimum value that the base width can take? b) Find the maximum threshold height that can be placed on the base without changing the channel width. c)...

Water (ρ-1000 kg/m3) flows in a rectangular channel over the 1 m drop. If the width of the channel is 1.5 m, determine the volumetric flow rate in the channel. Assume water is an ideal fluid. 0.5 m 1 m 2 m Figure 3
3. Water flows in a rectangular channel of width, w. In some cases, the water may suddenly increase in elevation as shown in the figure (from h to ha) through a highly disturbed region called a hydraulic jump. Assume the velocity is uniform at stations 1 and 2, and assume the pressures are distributed hydrostatically. Neglect friction on the channel bottom and sides. Hydraulic jump V2 Figure for problem 3. (a) Discuss the assumptions made in the problem statement. How...
