Question 3: Compound channel flow Consider the compound channel section below. - 17.0 n = 0.030...
Question 7 Consider flow in an open channel with slope 1:500 and a Manning's n of 0.030. The channel has a rectangular cross-section with a width of 5 m (a) Uniform flow in this channel has a depth of 1.6 m. What is the flowrate in the channel? (4 marks) (b) Suppose that this uniform flow (at point 1 in the figure below) encounters an obstacle on the channel bed (at point 2). How big would the obstacle need to...
please solve this problem 8. A rectangular channel section has a change in slope as shown in figure below. The chamel is 4m wide having Manning's n = 0.0165. The bed siope So,-0.0024 and the flowing discharge is 16 m,sec. a) Calculate the depth that must exrist in the downstream channe!l for a hydraulic jump to terminate at uniform fiow condition. b) If upstream depth Yoi 0.4m, calculate the length of hydraucump using at least three increments of depth in...
Question 6 A concrete-lined trapezoidal channel with uniform flow has a normal depth of 1.5 m. The base width is 4 m and the side slopes are equal at 1 vertical to 2 horizontal. Mannin‘s n-0015. The bed slope 0.001 Compute the mean velocity and discharge. If the above channel were to be designed for flooding, it may have a section like in Figure below 8 m 8 m 4 m When the flow goes over the top of the...
b. Data: y=1 m b= 5m S= 1/1000 n=0.02 Q-6.317 m^3/s V= 1.263 m/s c) At a point downstream of that in part (b) above, there is a weir, Az is 0.5 m in height. If the section properties of the channel remains the same as in part (b), determine yı the depth of flow just before the weir. Assume negligible headloss across the weir and critical flow occurs over the weir. (yı lies between 1.2 1.3 m) (8 Marks)...
could you help me with numbers 1-3 Question 1: Use the Repeating Method Only! Water sloshes back and forth in a tank as shown in the figure below. The frequency of sloshing. 6, is assumed to be a function of the acceleration of gravity. 8. the average depth of the water, h, and the length of the tank, C. Develop a suitable set of dimensionless parameters for this problem using g and l as repeating variables. Question 2, Flow with...
