Example
Determine the boundary layer thickness, the wall shear stress of a laminar water flow over a flat plate. The freestream velocity is 1 m/s, the kinematic viscosity of the water is 10-6 m2/s. The density of the water is 1,000 kg/m3. The transition Reynolds number Re=Ux/n=5?105. Determine the distance downstream of the leading edge when the boundary transitions to turbulent. Determine the total frictional drag produced by the laminar portion of the plate.
