Question 1
What is the equation used to find velocity in open channels according to Chezy's formula?
- V = R_h S^{1/2}
- V = C√R_h S^{1/2}
- V = R_h^{2/3} S^{1/2}
💡 Hint: Remember the relationship between velocity and flow characteristics.
Question 2
True or False: The hydraulic radius increases with the wetted perimeter.
- True
- False
💡 Hint: Think about the ratio of area to perimeter.

Challenge Problems
Push your limits with challenges.
Question 1
A rectangular open channel has a width of 5 m and a depth of 2 m. Calculate the flow velocity in the channel if the slope is 0.001 and the Manning’s roughness coefficient is 0.02. Use Manning's equation for your calculation.
💡 Hint: Remember to calculate area, wetted perimeter, and hydraulic radius first.
Question 2
Consider a trapezoidal channel where the bottom is 4 m, side slopes are 1:2, and the depth is 3 m. Calculate the area and the flow rate given that the slope is 0.002 and n is 0.015.
💡 Hint: Focus first on determining area and wetted perimeter.
