Define open channel flow.
Show hintHide hint
Think about rivers or channels without a cover.
Question 2.
What is the hydraulic radius?
Show hintHide hint
Recall the formula A/P.
3Question 3.
What is the primary difference between open channel flow and pipe flow?
- Open channels have pressure force
- while pipes do not
- Pipes have free surfaces
- while open channels do not
- Open channels have free surfaces
- while pipes have pressure forces
Show hintHide hint
Think about what constitutes each type of flow.
4Question 4.
True or False: The hydraulic gradient line in open channel flow is equivalent to the free surface.
- True
- False
Show hintHide hint
Consider what happens at the free surface level.
Question 5.
Design a channel that allows for uniform flow. Calculate the dimensions required to maintain a constant depth of 2m with a width of 8m.
Show hintHide hint
Make sure to analyze forces acting to achieve uniform flow.
Question 6.
A river experiences rapid changes due to a rainstorm. Describe the energy gradient line behavior during this transition.
Show hintHide hint
Think about how energy redistributes when flow characteristics change quickly.
