4- Two free vortices of equal strength, but opposite direction of rotation, are superimposed with a uniform flow as shown in Fig. 4 1. The stream functions for these two vorticies are = -[±I/(2)] In r. (a) Develop an equation for the xr-component of velocity, u, at point P(x.y) in tems of Cartesian coordinates x and y. (b) Compute the x-component of velocity at point A and show that it depends on the ratio I'/H. Sketch and describe the flow then determine the stagnation points. •Plx, y) H [A Figure (4) tttttt1
