Challenge Problems
Push your limits with challenges.
Question 1
Given a velocity distribution of u/U = (y/δ)², derive the expressions for displacement thickness, momentum thickness, and energy thickness.
💡 Hint: Start with displacement thickness first, then substitute into the other forms.
Question 2
Analyze a scenario where viscosity doubles, and calculate how this affects displacement and momentum thickness in a given flow profile.
💡 Hint: Evaluate how viscosity influences flow properties in your equations.
