1. The stream function for an incompressible, two-dimensional flow field is

For this flow field, sketch several streamlines.

2. A line vortex of strength K at (x, y)
 (0, a) is combined with opposite strength vortex at (0,
a): Plot the streamline pattern and find the velocity that each vortex induces on the other vortex.
