Consider the two-dimensional flow field in which u=Ax2 and υ=Bxy, where A=1=2 ft−1 s−1, B= −1 ft−1 s−1, and the coordinates are measured in feet. Show that the velocity field represents a possible incompressible flow. Determine the rotation at point ðx, yÞ=ð1,1Þ. Evaluate the circulation about the "curve" bounded by y=0, x=1, y=1, and x=0.
