The velocity profile in a turbulent boundary-layer flow at zero pressure gradient is approximated by the \(\frac{1}{6}\)-power profile expression,

\[\frac{u}{U}=\eta^{1 / 6}, \quad \text { where } \quad \eta=\frac{y}{\delta}\]

Use the momentum integral equation with this profile to obtain expressions for \(\delta / x\) and \(C_{f}\). Compare with results obtained for the \(\frac{1}{7}\)-power profile.
