The circumferential velocities in a free vertex and forced vortex, respectively, are u = C/r and u = wr, where the radius in meters, velocity is in m/s, and C is 8 m^2/s, and w = 2 rad/s. For both cases, calculate the circulation around a circular path with a radius of 1m and a center at (0,0). Are these inviscid flows? Note that ur = 0.
