Question

A sphere and a circular cylinder (with its axis perpendicular to the flow) are mounted in the same freestream. A pressure tap exists at the top of the sphere, and this is connected via a tube to one side of a manometer. The other side of the manometer is connected to a pressure tap on the surface of the cylinder. This tap is located on the cylindrical surface such that the deflection of the fluid in the manometer indicates that the pressure coefficient over the cylinder is 40% greater than that for the sphere. Calculate the location of this tap. (Round the final answer to two decimal places.) The pressure tap on the cylinder must be located at an angular position ° above or below the stagnation point.
