Question: 7 25 pts a consider water flowing at 6ms past...

Question details

7. (25 pts) (a) Consider water flowing at 6m/s past a 1m diameter circular cylinder. What doublet strength K is required to model this flow? If the far field pressure is 200kPa, use inviscid theory to estimate the surface pressure at θ equal to 1800 135, and 90° (b) Suppose that circulation is added to the cylinder flow, above, sufficient to place the stagnation points at θ equal to 350 and 1450, What is the required vortex strength Γ in mys? Compute the resulting pressure and surface velocities at the stagnation points and the upper and lower shoulders of the cylinder. What will the lift per meter of the cylinder width be?
