A potential flow source having an intensity of 10m2/s, placed in the point of Cartesian coordinates (1;0), and a sink having identical intensity, placed in the point (-1;0), are combined with a uniform flow at 25 m/s, in the direction -x (i.e., flowing from positive abscissae towards negative abscissae).
Find the width (in the x-direction) of the Rankine oval created by the flow, and the pressure difference between a point at infinite distance upstream and the point of coordinates (1,1).
