2. In an experiment to determine the force acting on a cylinder, a circular cylinder of diameter d and length f is mounted in the test section of an open wind tunnel. The cylinder is subject to a steady, uniform, incompressible flow of velocity V.. The velocity profile downstream of the cylinder is given as V = 2 1 - cos #4 . Use the control volume shown in the figure. Find the force acting on the cylinder. Compare your solution to that in problem 1. 2d Figure for problem 2
