HONG KONG UNIVERSITY OF SCIENCE AND TECHNOLOGY Department of Civil Engineering CIVL 252 – Hydraulics Prof. Mohamed S. Ghidaoui Open Channel-I 1. What is the mean shear stress over a wetted perimeter of a triangular channel flume 2.4 m deep and 3 m wide, when the depth of a uniform is 1.8 m? The slope of the flume is 1 in 200. 2. Uniform flow occurs in a rectangular channel 3 m wide at a depth of 1.8 m. If the Chezy coefficient C=66.25 m 0.5 /s, calculate the Manning coefficient n. 3. Calculate the uniform flowrate in an earth-lined trapezoidal canal having bottom width of 3 m, sides sloping 1 vertical to 2 horizontal, laid in a slope of 0.0001and having a depth of 1.8 m. 4. At what depth will 4.25 m 3 /s flow uniformly in a rectangular channel 3.6m wide? This channel is lined with rubble and has a slope of 1 to 4000. If this channel is 2km long, plot the EGL and the HGL. 5. An earth-lined trapezoidal canal of base width 3 m and side slopes 1 vertical to 3 horizontal is to carry a 2.8 m
