Question 1.
Define specific energy in terms of depth and velocity.
Show hintHide hint
What does specific energy account for?
Question 2.
What does head loss represent in an open channel?
Show hintHide hint
Think about why water slows down in channels.
3Question 3.
What is the formula for specific energy?
- A) E = y + V²/2g
- B) E = y - V²/2g
- C) E = y * V²/2g
Show hintHide hint
Remember how we combine potential and kinetic energy.
4Question 4.
True or False: Head loss increases the energy of flowing water.
- True
- False
Show hintHide hint
Consider what happens to energy in a frictional scenario.
Question 5.
A rectangular channel has a flow depth of 0.5 m and a width of 4 m. If the discharge is 8 m³/s, calculate its specific energy and determine if the flow is subcritical or supercritical.
Show hintHide hint
Use the relationship between discharge, area, and flow velocity.
Question 6.
Discuss how varying the slope of the channel impacts head loss and flow energy. Provide examples.
Show hintHide hint
Think about real-world applications like rivers or drainage systems.
