number that represents the intensity of force acting on a body in motion in direct opposition to the body's motion
The drag coefficient is defined as the drag/(dynamic pressure * reference area) The reference area is usually the plan-form or flat projection (the wing's shadow at noon) area of the wing
Normalized drag force, makes the comparison of the aerodynamic properties of different sized objects possible; Definition
A measure of the aerodynamic sleekness of an object Drag coefficient is signified by "dc : The lower the number, the greater the aerodynamic efficiency The higher the drag coefficient, the more a car's engine must work to keep a given road speed Also known as "CD" for coefficient of drag "
A coefficient representing the drag on a given airfoil or other body, or a coefficient representing a particular element of drag See Rayleigh formula
A dimensionless measure of the aerodynamic sleekness of an object A sleek car has a drag coefficient, or "Cd," of about 0 30; a square, flat plate's is 1 98 Also signified by Cx
the dimensionless ratio of the drag force on a body immersed in a fluid flow to the incident or adjacent fluid momentum flux
the ratio of the drag on a body moving through air to the product of the velocity and the surface area of the body
