Question 1.
What is the Froude number if the velocity is 3 m/s and depth is 0.5 m?
Show hintHide hint
Use the formula Fr = V / √(g * y).
Question 2.
Define the term 'head loss' in hydraulic jumps.
Show hintHide hint
Think about the energy changes in the flow system.
3Question 3.
What happens to the Froude number during a hydraulic jump?
- It decreases
- It increases
- It stays the same
Show hintHide hint
Think about how flow changes after the jump.
4Question 4.
True or False: A hydraulic jump only occurs if Fr1 is less than 1.
- True
- False
Show hintHide hint
Recall the conditions for jumps.
Question 5.
Calculate the discharge intensity and Froude number for a rectangular channel having a width of 3 m, carrying a discharge of 5 m³/s at a depth of 0.5 m.
Show hintHide hint
First, compute discharge intensity then find the Froude number.
Question 6.
Given a downstream depth of 0.75 m, what would be the corresponding upstream depth if Fr1 = 4?
Show hintHide hint
Substitute known variables into the equation for y2/y1.
