Aerodynamic Force
The force exerted by a moving gaseous fluid upon a body completely
immersed in it.
The aerodynamic force is proportional to the expression

where p is the fluid density; u is the velocity
of the undisturbed stream relative to the body; L is a characteristic
linear dimension of the body; and R^{n} is the Reynolds number raised
to the power of n, a constant usually determined experimentally.
This form for the aerodynamic force is sometimes called Rayleigh
formula. The component of the aerodynamic force parallel to the
direction of flow is called the drag.
