Using numerical results obtained by Blasius (Table 9.1, on the web), evaluate the vertical component of velocity in a laminar boundary layer on a flat plate. Plot \(v / U\) versus \(y / \delta\) for \(R e_{x}=10^{5}\).

Example 9.1 BOUNDARY LAYER IN CHANNEL FLOW A laboratory wind tunnel has a test section that is 305 mm square. Boundary-layer velocity profiles are measured at two cross- sections and displacement thicknesses are evaluated from the measured profiles. At section , where the freestream speed is U = 26m/s, the displacement thickness is = 1.5 mm. At section 2, located downstream from section , 82=2.1 mm. Cal- culate the change in static pressure between sections 1 and 2. Express the result as a fraction of the freestream dynamic pressure at section D. Assume standard atmosphere conditions.
