Question 1.
Define Stream Function.
Show hintHide hint
Think about how it relates to fluid flow.
Question 2.
Calculate the flow rate between stream functions ψ₁ = 5 and ψ₂ = 10.
Show hintHide hint
Use the difference method for flow rates.
3Question 3.
What is a stream function?
- A type of fluid
- A scalar function for streamlines
- A force acting on fluids
Show hintHide hint
Think about how it's used in fluid dynamics.
4Question 4.
Flow rate is calculated by which method?
- True
- False
Show hintHide hint
Recall how we calculate flow rate.
Question 5.
If φ is defined as φ = x^2 - 3xy + y^2, derive the stream function and then calculate the flow rate between points (2,1) and (2,2).
Show hintHide hint
Start by finding u and v using partial derivatives.
Question 6.
Given φ = xy^2 - x^2 + 2y, determine how to express ψ and then compute the flow rate between the streamline at points (1,1) and (1,2).
Show hintHide hint
Remember to integrate correctly to get ψ from the velocity potential φ.
