Question 1.
What does the continuity equation represent in fluid dynamics?
Show hintHide hint
Consider the relationship between area and velocity.
Question 2.
What is the definition of vorticity?
Show hintHide hint
Think about the angular motion of fluid elements.
3Question 3.
What is the condition for flow to be considered irrotational?
- At least one component of vorticity is non-zero
- All components of vorticity are zero
- Vorticity is greater than a certain threshold
Show hintHide hint
Recall the definition of irrotational flow.
4Question 4.
True or False: A rotational flow can have zero vorticity.
- True
- False
Show hintHide hint
Consider the nature of vorticity in flow.
Question 5.
Given a fluid flow with velocity components u = y^2, v = -x and w = 0, determine the vorticity components and classify the flow.
Show hintHide hint
Apply the definitions provided in the section.
Question 6.
Investigate if a flow characterized by a potential function phi = x^3 - 3xy^2 is irrotational. What are its implications?
Show hintHide hint
Recall the implications of potential functions as discussed.
