The drag coefficient with normal force coefficient is a formula that relates the drag force acting on a body in a fluid flow to the normal force coefficient and the angle of attack of the body. The normal force coefficient is a dimensionless quantity that measures the normal force acting on the body per unit dynamic pressure and reference area. The angle of attack is the angle between the free-stream velocity vector and the chord line of the body.
