For the flow conditions of Example 9.4, but using the 1

6-

power velocity profile of Problem 9.60, develop an algebraic

expression for the variation of wall shear stress with distance

along the surface. Integrate to obtain an algebraic expression

for the total skin friction drag on the surface. Evaluate the

drag for the given conditions.
