Question 1
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).
💡 Hint: Start by finding u and v using partial derivatives.
Question 2
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).
💡 Hint: Remember to integrate correctly to get ψ from the velocity potential φ.
