 FLUID MECHANICS - CASE STUDY SOLUTION Streamlines for the Case Study Streamlines are lines tangent to the velocities, hence      dy/dx = v/u = -x/y The above equation can be integrated to yield       where c' and c are arbitrary constants (c2 = 2c' ). Thus, the obtained streamlines are concentric circles, as shown in the figure. Since the flow is steady (independent of time), the pathlines and streaklines are identical to the streamlines.
