Consider inviscid, incompressible flow over a closed semi-cylinder with radius 0.5m. Assume the flow field over the top of the semi-cylinder is identical to the flow over a cylinder for Osesn. Assume the pressure on the bottom of the semi-cylinder is stagnation pressure, po. The freestream velocity is 3 m/s and the density is 1.23 kg/m?. a) What is the net lift force acting on the semi-cylinder? U b) What is the net drag force acting on the semi-cylinder? P. Now consider that the flow is viscous, but still incompressible and that the dynamic viscosity is 2x10 kg/(m*s). c) Estimate the drag on the semi-cylinder assuming it is equivalent to % the drag of a cylinder. Recall that Co=f(Re) for a cylinder as shown below. d) Do you estimate the boundary layer to be laminar or turbulent in part (c) and why? tttt
