Drag Coefficient

Drag coefficient is proportional to { (gravitational force) / (inertial force) } and is used in momentum transfer in general and free settling velocities and resistance to flow calculations in particular. It is normally defined in the following form :

 

Drag Coefficient

 

Where:

g

=

Gravitational acceleration

L

=

Characteristic dimension of object

rho

=

Density of object

rho_f

=

Density of surrounding fluid

V

=

Velocity
