Challenge Problems
Push your limits with challenges.
Question 1
Demonstrate how to derive one velocity component from a given velocity potential. Use φ(x, y) = x² + y² as your potential function.
💡 Hint: Make sure to apply the partial derivative correctly.
Question 2
Assume a fluid field where it shows evident vorticity; explain why velocity potentials cannot be employed effectively here.
💡 Hint: Consider how vorticity is indicative of turbulence.
