Question

4. Suppose that the velocity distribution within a pipe can be described by theexpression below: V(r)=V_{o}\left(1-\frac{r^{2}}{R^{2}}\right) Where:r- distance from the center of the pipe R- nine radius Vo - pipe centerline velocity a) The location where the shear stress is a minimum b) The location where the shear stress is a maximum c)The shear stress anywhere within the pipeline
