3) Sea water U = 1 m/s flows over a sand ridge 2 m high in steady, uniform, incompressible, inviscid, irrotational flow. What is the flow velocity @ (r=2.25 m, 0 = 3/4)? Use Uniform Flow and Doublet Stream Function. 25 pts Extra credit: what is the pressure drop along the streamline passing through that point relative to the far field flow? 10 pts r = 2.25m = 1.5 2.25m
