Show that the potential function = (Ar + B/r)cose gives the flow of an ideal fluid around a cylinder. Determine the constants A and B if the velocity of the main stream is u and the cylinder is radius R. b. Find the pressure distribution around the cylinder expressed in the form (p-p')/(pu2/2) as a function of angle. c. Sketch the relationship derived above and compare it with the actual pressure profiles that occur up to a Reynolds number of 5 x 105.
