Question 1
Given a flat plate with a flow profile defined as u/U = 3y/delta - 2y^2/delta^2, calculate the displacement, momentum, and energy thickness. Show all work and derive the necessary formulas.
💡 Hint: Break the problem down into steps and apply the related formulas discussed.
Question 2
In turbulent flow, discuss how the boundary layer differs compared to laminar flow. Why are thickness measurements critical in engineering applications?
💡 Hint: Consider how turbulent changes lead to variations in viscous effects.
