Consider laminar steady boundary layer at a flat plate. Assume the velocity profile in the boundary layer as parabolic, u(y)=U(2 (y/δ)-(y/δ)^2). 1. Calculate the thickness of the boundary layer, δ(x), as a function of Reynold's number. 2. Calculate the shear stress at the surface, τ, as a function of Reynold's number. Re=ρUx/μ

The local convection coefficient on a plate decreases as the thickness of the boundary layer grows along the plate. After transition from laminar to turbulent flow, the local convection coefficient becomes much larger, even though the boundary layer is much thicker. Explain why this is so. Explain with a paragraph in a clear and straightforward manner, please.
