1. Calculate the displacement and momentum thickness for the preceding velocity profile and compare with the exact results.
2. Calculate the local shear stress and friction coefficient for the preceding velocity profile and compare with the exact results.
3. Suppose that the velocity profile proposed for a turbulent boundary layer has the form
