Challenge Problems
Push your limits with challenges.
Question 1
A water flow between two parallel plates has the velocity described by u = h^2/(2μ)(1 - (y^2/h^2)). Calculate the wall shear stress at y = h.
💡 Hint: Consider the relationship to the viscosity and velocity gradient.
Question 2
If the vorticity is not zero in a flow field, can you find the velocity potential function? Justify your answer.
💡 Hint: Reflect on irrotational flow characteristics.
