Show hintHide hint
Think about what it compares.
Question 2.
What defines subcritical flow?
Show hintHide hint
What happens to wave propagation in this flow?
3Question 3.
What is the Froude number?
- Ratio of velocity to gravity
- Dimensionless ratio for flow regime
- Calculates depth only
Show hintHide hint
What does it evaluate in hydraulic engineering?
4Question 4.
True or False: Supercritical flows allow waves to travel upstream.
- True
- False
Show hintHide hint
Consider the flow speed.
Question 5.
A river with varying depths presents flow speeds at different points. Calculate the flow regime at a section where the Froude number is found to be 0.85.
Show hintHide hint
Assess the characteristics of your flow calculation.
Question 6.
In a proposed dam design, water flow is expected to shift from supercritical to subcritical. What engineering adjustments should be made?
Show hintHide hint
Think about flow characteristics and water management.
