For a flow in the xy plane, the x component of velocity is given by u = Ax^2y^2, where A = 0.3 m^-3s^-1, and x and y are measured in meters. Find a possible y component for steady, incompressible flow. Is it also valid for unsteady, incompressible flow? Why? How many possible y components are there? Determine the equation of the streamline for the simplest y component of velocity. Plot the streamlines.
