The x and y components of a velocity field are given by u = 5y/(x^2 + y^2) and v = (-5x/(x^2 + y^2). Calculate the circulation around a circular path of radius 3m. Let the units of u and v be in m/s.
Consider a velocity field where x and y components of velocity are $u = 5y/\left( {{x^2} + {y^2}} \right)$ and \(v = …
