The velocity profile inside the boundary layer for flow over a flat plate is given as $\frac{u}{U_{\infty}} = \sin \left(\frac{\pi y}{2 \delta}\right)$, where $U_{\infty}$ is the f...

The velocity profile inside the boundary layer for flow over a flat plate is given as $${u \over {{U_\infty }}} = \sin \left( {{\pi \over 2}\,{y \over \delta }} \right),$$ where $$...
