The drag coefficient (C) is determined from terminal velocity, density of the medium, projected area and mass of the object.
Terminal velocity is the constant speed of a freely falling object when the resistance of the medium through which it is falling prevents further acceleration.
The magnitude of terminal velocity is calculated as;
[tex]V_T = \sqrt{\frac{2mg}{\rho A C} }[/tex]
where;
Thus, the drag coefficient (C) is determined from terminal velocity, density of the medium, projected area and mass of the object.
