Chapter 20, Problem 57P

The velocity u of air flowing past a flat surface is measuredat several distances y away from the surface. Fit a curve to thesedata assuming that the velocity is zero at the surface $\left(y=0\right)$. Useyour result to determine the shear stress $\left(\mu du/dy\right)$ at the surface. $\left(\mu =1.8\times {10}^{-5}\text{N}\cdot {\text{s/m}}^{\text{2}}\right)$
