The drag force acting on the cylinder was measured using a multi-tube well type manometer. The small holes are drilled in the surface of the cylinder which are attached to small tubes. The tubes are connected to the manometer tubes to measure the pressure distribution on the cylinder immersed in a flow. The pressure is assumed to remain constant over each segment and the force is given by 36 F = LP (cos + sin j)R - k=1 10-2 360 Wind Leading edge (a) Pressure distribution is acquired as below. Locate the position of the leading edge on the graph below. [2 pts] -0.05 leading edge Pressure (psi) -0.1 -0.15 -0.2 -0.25 -0.3 -0.35 -0.4 -0.45 Pressure Tap No. 98 ft/s (b) Assume that you measure the drag force on the circular cylinder using a dynamometer (as you did in Lift and Drag Measurements of an airfoil Lab). The cylinder is mounted on a sting to transmit the force into the dynamometer. In this experiment, do you expect the drag force with the dynamometer to be higher or lower than the drag force you originally measured with the manometers? Explain. Disregard the effect of sting on the drag measurement. [8 pts]
