Challenge Problems
Push your limits with challenges.
Question 1
Given the stream function ψ = r²sin(θ), find the velocity components and demonstrate how the flow behaves in a radial direction.
💡 Hint: Utilize polar derivatives to solve.
Question 2
Analyze a cylindrical tank where the velocity of fluid outflow varies with height. Using stream functions, determine how this affects the preservation of mass.
💡 Hint: Remember that mass in equals mass out for steady flow.
