Question 1.
Define supercritical flow.
Show hintHide hint
Think about the definitions of flow speed and wave speed.
Question 2.
What is specific energy?
Show hintHide hint
Consider what components of energy contribute to fluid flow.
3Question 3.
What Froude number indicates supercritical flow?
- Less than 1
- Equal to 1
- Greater than 1
Show hintHide hint
Remember the criteria for each flow type.
4Question 4.
True or False: Energy is always conserved during hydraulic jumps.
- True
- False
Show hintHide hint
Consider the energy changes in transition from supercritical to subcritical.
Question 5.
A rectangular canal has a width of 10m and carries water at 2m depth with a velocity of 4m/s. Calculate the Froude number and classify the flow.
Show hintHide hint
Use the formula for Froude number mentioned earlier.
Question 6.
In a hydraulic jump scenario, if upstream velocity is 5 m/s and downstream field has flow depth of 1.5 m, determine the energy loss if initial depth was 3m.
Show hintHide hint
Remember the specific energy formula and how to find velocity at downstream.
