Question 1.
What does it mean for a fluid to be considered ideal?
Show hintHide hint
Consider how real fluids behave under friction.
Question 2.
Explain irrotational flow in your own words.
Show hintHide hint
Think about how whirlpools differ in flow.
3Question 3.
What does the term 'ideal fluid' refer to?
- A fluid with viscosity
- A fluid with no viscosity
- A real-world fluid
Show hintHide hint
Consider what is meant by frictionless flows.
4Question 4.
True or False: Surface tension is negligible in all fluid dynamic scenarios.
- True
- False
Show hintHide hint
Think about different contexts for small versus large waves.
Question 5.
Consider a case where water waves are propagating on a lake surface. If we assume irrotational flow, how would energy dissipation differ in real versus ideal fluids?
Show hintHide hint
Think about where energy goes in real flows and compare with ideal assumptions.
Question 6.
You’ve modeled a situation neglecting surface tension in a fluid. What scenarios could this lead to erroneous predictions, and how could you address this issue?
Show hintHide hint
Focus on environments where surface tension could be critically influencing.
