Show hintHide hint
Think about what defines a surface in water flow.
Question 2.
What are the two main forces in open channel flow?
Show hintHide hint
Consider the forces acting on the water in the channel.
3Question 3.
What is the pressure at the free surface of an open channel flow?
- Internal pressure
- Atmospheric pressure
- No pressure
Show hintHide hint
Consider what type of pressure affects the top of the water.
4Question 4.

Question 5.
Given a trapezoidal channel with a bottom width of 5 m, side slopes of 2:1, and a flow depth of 3 m, calculate the hydraulic radius.
Show hintHide hint
Use trapezoidal area and perimeter formulas to find R.
Question 6.
Analyze the effect of increasing friction on open channel flow velocity. How would this change relate to flow conditions?
