Flashcard drill
4 cards from this lesson. Good the night before a test.
Try these first
- 1.
Define the continuity equation.
Hint
Think about the conservation of mass.
- 2.
What is a stream function?
Hint
It helps visualize flow patterns.
- 3.
What does the continuity equation ensure in fluid flow?
- Mass flow is variably changed.
- Mass flow is constant.
- Fluid density varies.
Hint
Consider mass conservation.
- 4.
Is irrotational flow characterized by non-zero vorticity?
- True
- False
Hint
Remember what irrotational means.
- 5.
Given a velocity potential of φ = x^2 + y^2, derive both the stream function and the flow rate between two points.
Hint
Use partial derivatives, and don’t forget to integrate.
- 6.
Analyze a scenario where water flows through a pipe with varying diameter using the principles of the continuity equation; what might happen at the convergence?
Hint
Think about conservation and how fluid must adjust!
