If the average velocity of flow is not to exceed 1m/s, find; The wetted perimeter for minimum amount of lining.                                   (10 Marks)Bed slope assuming Manning’s    N=0.015                                                  (10 marks)

Determine the depth in m of the trapezoidal channel with sides inclined 45 deg with the horizontal to prevent scouring with a maximum velocity of 3 m/s and a flow of 225 cum/sec. Use 1-decimal place.

Water is to flow at a rate of 30m3 /s in the concrete (n=0.013) channel shown below. Find the required vertical drop of the channel bottom per kilometre of length.

What flow can be exerted in a 1.2m wide rectangular, cement lined channel (n=0.015)laid on a slope of 4m in 10km, if the water flows 0.6m deep?

For a V-shaped concrete lined channel with total included angle of 80°, and a depth of 3m if the discharge is 10.7m³/s. Determine the slope if Darcy-Weisbach constant is 0.011 Pls show complete solution and diagram. (Answer should be in fraction) Thank you

Calculate the equivalent normal depth of the most efficient trapezoidal section corresponding to the most efficient rectangular section having a normal depth of 1.75m assuming both channels will be constructed of the same material and laid on the same slope.

The flowrate in the clay-lined channel (n = 0.025) is to be 8.5 m3 /s. To prevent erosion of the sides, the velocity must not exceed 1.5 m/s. For this maximum velocity, determine the width of the bottom b and slope S0

Design a most efficient trapezoidal channel section with velocity 0.6 m/s, side slope 2:1, longitudinal slope of 1 in 5000, discharge 30 m3 /s. Assume manning’s coefficient as a concrete lined canal.

A rectangular channel of best hydraulic cross-section, n = 0.016, is laid on a slope of 0.0064 and carries 98 m³/ s. For critical conditions, what with is required?

Water flows at the rate of 25 in a trapezoidal channel having a base width of 3 m and side slope of 4H:3V. If the canal is lined with the m³ concrete (n = 0.013) , determine: (a) critical depth, (b) critical velocity, c.) critical slope. To solve for the critical depth, you may use the formula: up to the water surface. (Q ^ 2)/g = (A ^ 3)/B where the critical depth is the height of the water from the channel bed
