Question 1.
Define the continuity equation.
Show hintHide hint
Think about the conservation of mass.
Question 2.
What is a stream function?
Show hintHide hint
It helps visualize flow patterns.
3Question 3.
What does the continuity equation ensure in fluid flow?
- Mass flow is variably changed.
- Mass flow is constant.
- Fluid density varies.
Show hintHide hint
Consider mass conservation.
4Question 4.
Is irrotational flow characterized by non-zero vorticity?
- True
- False
Show hintHide hint
Remember what irrotational means.
Question 5.
Given a velocity potential of φ = x^2 + y^2, derive both the stream function and the flow rate between two points.
Show hintHide hint
Use partial derivatives, and don’t forget to integrate.
Question 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?
Show hintHide hint
Think about conservation and how fluid must adjust!
