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.
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.
