For #5-7, assume there is a creek with a width of 4.6 m, depth of 23 cm, slope of 0.001 m/m, and discharge of 0.13 m³/s. 5. Assuming a rectangular cross section, what is the hydraulic radius of the creek to the nearest cm? 6. What is the average flow velocity to the nearest cm/s? 7. And what is the channel's Manning's roughness coefficient (using SI units) to the nearest hundredth?

1. Dikes are to be installed on both channel banks of the 1.2 km long river section. The river width is 60 m, and 50% of the river width should be secured for flow passage. Determine the number of dikes can be installed in this section. Use the Winkel's formula and the angle from the front of the dike to the bottom of the next dike is 10 degrees.

A concrete pipe culvert is to be constructed under road to carry a maximum discharge 9 m3 /sec. If the length of pipe culvert 10 m on slope 1/100, ?? = 0.5, ?? = 1, n = 0.018, ?? = 0.18. Find the diameter of the pipe.

Manning's equation is Q = where Cm AR 2/3 1/2 n Q = Cm = = flow (m³/s) 1.49 USC system 1.00 SI system roughness factor for various boundary conditions area (m2) hydraulic radius (m) n = A = R == = S = slope of EGL (or HGL for steady uniform flow conditions) m/m area/wetted perimeter Transform the above equation to solve for pipe diameter (mm) expressed in terms of flow (L/s), pipe slope (%) and pipe roughness "n". The value of Cm 1s 1.00 for a metric equation. Express your answer in the simplest form mathematically. Check by assuming arbitrary values and comparing the results between the original equation and the transformed equation.

A hydraulic jump occurs on a circular channel with diameter of 15 ft and discharge of Q = 1000 cfs. The flow depth is 3 ft upstream. Find the depth after the jump graphically.

A weir installed at the end of a rectangular channel controls the flow of water. The rate of flow is 0.62 m^3/s. If the error in measuring the head is 0.018m, determine the percentage error in the measured flow if a 90 degree V-notch weir is used. (A) 6.35% B) 7.12% 6.92% 5.45%

Q.

answer is given just give the solution and right answer.

, in two columns, and box your final answer. 1. A concrete channel, rectangular in shape, is laid on a channel bed of slope 0.0010. At an upstreampoint, the depth of water is 1.5 m and 300 meters away, at a downstream point, the depth of flow becomes 1.17 m. If the channel is 4.5 m wide, and has the roughness coefficient of 0.013, find the approximate flow rate.

Note:hand written solution should be avoided.
