Question: Using Blasius correlation for shear stress (equation (12-68)), develop an expression for the local skin-friction coefficient in pipes. In pipes, the average velocity is used

Using Blasius€™ correlation for shear stress (equation (12-68)), develop an expression for the local skin-friction coefficient in pipes. In pipes, the average velocity is used for the friction coefficient and the Reynolds number. Use the one seventh-power law.
