Question 1.
What is the formula to calculate the Froude number?
Show hintHide hint
Think about how velocity relates to wave speed in a channel.
Question 2.
Define the term 'specific energy.'
Show hintHide hint
What two components make up the specific energy?
3Question 3.
What does a Froude number less than 1 indicate?
- Subcritical flow
- Supercritical flow
- Critical flow
Show hintHide hint
Think about the characteristics of subcritical flow.
4Question 4.
True or False: The specific energy is always constant in an open channel.
- True
- False
Show hintHide hint
Consider how energy behaves under different circumstances.
Question 5.
A river with a known depth of 1.5 m and velocity of 4 m/s has to be analyzed for critical flow application. Determine if the flow is subcritical, supercritical or critical.
Show hintHide hint
Find the Froude number to determine flow conditions.
Question 6.
Given a rectangular channel 3 m wide with a total discharge of 9 m³/s, find the critical depth and specific energy at that depth.
Show hintHide hint
Investigate the depth and apply discharge to arrive at energy calculations.
