2. Consider the potential flow resulting from the superposition of a uniform stream and the fields of a line source with strength 24 and a line sink with strength - A, as shown in the figure. Let A = 2Vxo. (a) Explain whether this could represent the flow about a closed, two-dimensional object or an infinite object. (b) Are there any stagnation points off the x-axis? (c) Are there any stagnation points on the x-axis? If yes, find them and try to sketch the shape of the stagnation streamline. Voo 24 K- xo -A X
