Unformatted text preview: Background/Theory: The term drag is referred to the opposing forces of the movement of the object that is traveling against a flow of fluid. Drag opposes the velocity of the flow, and it is determined by the velocity and static pressure of the upstream, as well as the downstream. There are different types of drag, like the skin drag, form drag, and lift-induced drag. The skin drag is the friction between the fluid and the skin of the object which influences the drag. The form drag is the shape and form of the object which takes the cross section of the area which contributes to the drag, bigger the object, the higher the drag. Lastly, the lift-induced drag refers to the object redirecting the flow of the fluid based on the angle of the object. The pressure distribution around a cylinder is characterized as inviscid flow, laminar boundary layer, and turbulent boundary layer. Upon gathering static pressure readings corresponding to various angles taken from the origin, the dimensionless pressure coefficient can be calculated.dimensionless pressure coefficient can be calculated....
