Question 1.
What is the formula for specific energy?
Show hintHide hint
Think about how depth and elevation contribute to overall energy.
Question 2.
Define subcritical flow.
Show hintHide hint
Consider the relationship between velocity and energy.
3Question 3.
What is specific energy?
- Energy per unit mass
- Energy per unit time
- Energy per unit weight
Show hintHide hint
Think about energy related to weight rather than mass.
4Question 4.
True or False: Supercritical flow always occurs at a higher depth compared to subcritical flow.
- True
- False
Show hintHide hint
Remember the relationship between depth and flow velocity.
Question 5.
Given a rectangular channel with a flow rate of 6 feet²/s and a depth of 2.5 feet, calculate y2 using Bernoulli's equation and describe the implications of your results.
Show hintHide hint
Set up the equations clearly, combine and rearrange.
Question 6.
If the ramp's height is increased to 0.75 feet, discuss how this affects flow regimes and specific energy calculations.
Show hintHide hint
Consider the principles learned about energy and physical flow behavior.
