Problem 2 (50 pts) Consider the following two-dimensional flow pattern: 3U(x2 - y2); _ 60xy L2 -- L2 (1) (ii) Show that this is an inviscid flow by determining the stream function y and proving 12 y = 0 Plot the streamlines and isobars (lines of constant pressure) for this flow in the first quadrant (x,y >0) assume the flow has no elevation change
