Question 1.
What is the formula to calculate the Froude number?
Show hintHide hint
Think about the relationship between velocity, gravity, and depth.
Question 2.
What is the flow regime when Fr < 1?
Show hintHide hint
Consider what happens to flow characteristics with increased depth.
3Question 3.
What is the definition of the Froude number?
- A measure of pressure
- A dimensionless quantity comparing inertia to gravity
- A calculation of fluid viscosity
Show hintHide hint
Reflect on what the Froude number compares.
4Question 4.
True or False: Supercritical flow occurs when the Froude number is less than 1.
- True
- False
Show hintHide hint
Consider the definitions of subcritical and supercritical flow.
Question 5.
A rectangular channel has a flow velocity of 4 m/s and a depth of 1.5 m. Calculate the Froude number and explain the implications for flow conditions.
Show hintHide hint
Use the flow definition with inertia relating to gravity.
Question 6.
In a river, the slope is adjusted from 1% to 3%. Discuss how this change affects the Froude number and what flow regime is expected.
Show hintHide hint
Consider how gravity influences motion and the inertia of the water.
