Quick quizzes to reinforce your learning

Question 1

What is the formula for calculating discharge using Manning's equation?

Q = (1/n) AR^(2/3) S0^(1/2)
Q = nAR^(1/2) S0^(1/3)
Q = n(A^2/P)^(1/3) S0^(1/2)

💡 Hint: Identify the variables: Q is discharge, n is roughness coefficient.

Question 2

The hydraulic radius is defined as?

True
False

💡 Hint: Think about the flow configuration.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A trapezoidal channel has a bottom width of 8 meters and depth of 2 meters, side slopes of 1:1. Calculate the discharge if n=0.013 and slope is known.

💡 Hint: Ensure you calculate the hydraulic radius correctly.

Challenge 2 Hard

Using the principles of a circular channel, derive the expression for the wetted perimeter given a half circle depth, and apply it to find discharge.

💡 Hint: Be careful with angle calculations to avoid errors with trigonometric functions.
