Using numerical results obtained by Blasius (Table 9.1, on the web), evaluate the distribution of shear stress in a laminar boundary layer on a flat plate. Plot \(\tau / \tau_{w}\) versus \(y / \delta\). Compare with results derived from the approximate parabolic velocity profile given in Problem 9.8.
