Question 1.
What is Bernoulli's principle?
Show hintHide hint
Think about energy conservation in fluid dynamics.
Question 2.
Explain what specific energy means.
Show hintHide hint
Combine potential and kinetic energy for your answer.
3Question 3.
What does Bernoulli's equation help determine?
- Flow rate
- Water elevation
- Pressure only
Show hintHide hint
Think about what we're solving for in channel flow.
4Question 4.
Is specific energy constant during flow changes in a channel?
- True
- False
Show hintHide hint
How does changing flow conditions affect energy?
Question 5.
Calculate the downstream elevation if water's upstream depth is 2.3 ft and the calculated velocity v1 is 2.5 ft/s, assuming energy loss from ramp is negligible.
Show hintHide hint
Use the specific energy relationships to establish your equations.
Question 6.
Consider a ramp with specific energy values derived. If y1 = 2.3 ft yields E = 3.03 ft at the beginning, calculate the new specific energy if the downstream flow depth fluctuates.
Show hintHide hint
Connect flow conditions to these energy variations.
