Consider two-dimensional potential flow into a step contraction as in Fig. The inlet velocity U1 = 7 m/s, and the outlet velocity U2 is uniform. The nodes (i, j) are labelled in the figure. Set up the complete finite-difference algebraic relation for all nodes. Solve, if possible, on a digital computer and plot the streamlines
