6 sample questions

Question 1.
What is the formula for calculating area in a trapezoidal channel?
Show hintHide hint
Think of how we calculate areas of triangles and rectangles together.
Question 2.
Define wetted perimeter (P).
Show hintHide hint
Consider all sides of the channel that the water touches.
3Question 3.
What is the hydraulic radius?
- A / P
- P / A
- A + P
Show hintHide hint
Remember how these terms relate to the flow in a channel.
4Question 4.
Is Manning's equation used for both circular and trapezoidal flow calculations?
- True
- False
Show hintHide hint
Think about the versatility of this equation.
Question 5.
Calculate the discharge for a trapezoidal channel with a bottom width of 8m, depth of 2m, and a side slope of 1:2. Given n = 0.015 and S₀ = 0.002.
Show hintHide hint
Break it into steps: Area first, then perimeter, finally use Manning's equation.
Question 6.
For a circular pipe with a diameter of 1.0m and flow depth of 0.4m, calculate the discharge using n = 0.013 and S₀ = 1/1000.
Show hintHide hint
Focus on finding theta to determine the submerged area.
