Question 1.
What is a stream function and how does it relate to fluid flow?
Show hintHide hint
Think about the paths followed by fluid particles.
Question 2.
Define mass conservation in your own words.
Show hintHide hint
Consider the closed system scenario.
3Question 3.
What is the role of stream functions in fluid mechanics?
- To visualize fluid flow
- To complicate fluid analysis
- To describe only incompressible flows
Show hintHide hint
Think about their fundamental purpose.
4Question 4.
Is it true or false that mass conservation states that mass can be created in a closed system?
- True
- False
Show hintHide hint
Recall the basic principle of closed systems.
Question 5.
A fluid flows around a building modeled by a simplified square shape. Using stream functions, derive the velocity components along the edges.
Show hintHide hint
Consider the geometry of the problem.
Question 6.
In a hypothetical scenario, a rotating cylinder is placed in a fluid. Using stream functions, explain how you would analyze the flow field.
Show hintHide hint
Think about how boundary conditions affect the flow.
