Question

3. For the following two-dimensional flow, plot the velocity vectors and contours of the divergence of the velocity on the same graph. Use ""meshgrid"" with a spacing of ""0.5"". 1 Last Name A-M: $V_x = frac{1}{sqrt{x^2 + y^2}}$, $V_y = frac{-xy}{sqrt{x^2 + y^2}}$ in the region $-4 < x < 4$, $-4 < y < 4$ Last Name N-Z: $V_x = frac{x}{sqrt{x^2 + y^2}}$, $V_y = frac{-y}{sqrt{x^2 + y^2}}$ in the region $-6 < x < 6$, $-6 < y < 6$ 4. For the two-dimensional flows from problem 3, plot 15 contours the angular velocity using the MATLAB command ""cav=curl(x, y, vx, vy)"". Use ""meshgrid"" with a spacing of ""0.2"".
