Question 1.
What is open channel flow?
Show hintHide hint
Think of natural rivers or ditches.
Question 2.
Define the hydraulic radius.
Show hintHide hint
Consider the influence of water on the channel's shape.
3Question 3.
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)
Show hintHide hint
Identify the variables: Q is discharge, n is roughness coefficient.
4Question 4.
The hydraulic radius is defined as?
- True
- False
Show hintHide hint
Think about the flow configuration.
Question 5.
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.
Show hintHide hint
Ensure you calculate the hydraulic radius correctly.
Question 6.
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.
