Consider a velocity field where the x and y components of velocity aregiven by u = cx/(x2 + y2) and v = cy/(x2 + y2) where c is a constant.              For source flow, calculate: a. The time rate of change of the volume of a fluid element per unitvolume.b. The vorticity.Hint: It is simpler to convert the velocity components to polar coordinatesand deal with a polar coordinate system.
