6 sample questions

Question 1.
What is the Froude number if the velocity is 5 m/s and depth is 2 m?
Show hintHide hint
Use the formula Fr = V / √(gy).
Question 2.
What happens to the flow when the Froude number exceeds 1?
Show hintHide hint
Remember the classification of flow based on Froude number.
3Question 3.
What does a Froude number greater than 1 indicate?
- Subcritical flow
- Supercritical flow
- Critical flow
Show hintHide hint
Think about the flow characteristics.
4Question 4.
True or False: A hydraulic jump only occurs when flow transitions from subcritical to supercritical.
- True
- False
Show hintHide hint
Remember the definition of hydraulic jumps.
Question 5.
In a spillway, the flow has a Froude number of 8, and depth before the jump is 2.5 meters. Calculate the depth after the jump and energy loss.
Show hintHide hint
Follow the depth ratio and energy loss equations as derived.
Question 6.
A rectangular channel has a velocity of 10 m/s and a depth of 1 meter before the jump. Determine Froude number before and after the jump if y2 is 5 meters.
Show hintHide hint
Balance flow equations while transforming for velocities.
