Unformatted text preview: Experimental Methods in Mechanical Engineering MEASUREMENT OF DRAG COEFFICIENTS Name: Samet Name: Samet Surname: Konu Surname: Konu Number: 030030010 Number: 030030010 Group : 11-13 Friday Group : 11-13 Friday Aim of the Experiment The aim of this experiment is to measure the drag forces on models of different shapes and calculate the drag coefficients as a function of “Re” number. Introduction When there is a motion between a solid body and a fluid, the body experiences a net force due to the action of the fluid. The component of force parallel to the direction of motion is the drag force and the component of force perpendicular to the direction of motion is the lift force. The force depends on the shape, attitude and size of the body, the density and viscosity of the fluid, and the velocity of relative motion. To measure the velocity of the flow we use a Pitot-tube. Knowledge of the values of the static and the stagnation pressure in a fluid implies that the fluid speed can be...
