Question 1.
Define specific energy.
Show hintHide hint
Refer to the formula involving height and velocity.
Question 2.
What characterizes subcritical flow?
Show hintHide hint
Think about flow speed in quiet channels.
3Question 3.
What is specific energy?
- Potential energy only
- Total energy per unit weight
- Kinetic energy only
Show hintHide hint
Think about the formula connecting depth and velocity.
4Question 4.
True or False: In subcritical flow, the specific energy is low.
- True
- False
Show hintHide hint
Look back at the definitions of flow states.
Question 5.
Calculate the total energy for a channel with a uniform depth of 4 ft and velocity of 5 ft/s under gravitational acceleration of 32.2 ft/s².
Show hintHide hint
Plug in depth and velocity correctly into the specific energy formula.
Question 6.
Design a minim-sized channel with a width of 2 ft that can sustain a flow rate of 10 ft²/s and calculate its downstream conditions.
Show hintHide hint
Use q = A * v for flow calculations, A being width times depth.
