Challenge Problems
Push your limits with challenges.
Question 1
Calculate the velocity profile for flow between two parallel plates with one moving and one at rest. Use the Navier-Stokes equations and apply relevant approximations.
💡 Hint: Assume no gravity, steady flow, and apply boundary conditions at both plates.
Question 2
Discuss the impact of a boundary layer on aerodynamic drag for an aircraft. Include concepts of shear stress and potential flow.
💡 Hint: link boundary layer behavior to coefficients of drag.
