Estimate the hydrodynamic force exerted on the upstream half of a vertical

1. To the two-dimensional infinite flow given by ψ = −Uy are added two sources, each of strength m, placed at (0, a) and (0, −a) respectively. If m > |2πUa|, determine the stream function of the combined flow and the position of any stagnation points. Sketch the resulting body contour and determine the velocity at the point where the contour cuts the y-axis.

2. Estimate the hydrodynamic force exerted on the upstream half of a vertical, cylindrical bridge pier 1.8 m diameter in a wide river 3 m deep which flows at a mean velocity of 1.2 m ·s−1.
