The streamlines for an incompressible, inviscid, two dimensional flow field are all concentric circles, and the velocity varies directly with the distance from the common center of the streamlines; that is

where K is a constant. (a) For this rotational flow, determine, if possible, the stream function. (b) Can the pressure difference between the origin and any other point be determined from the Bernoulli equation? Explain.
