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 :
Where: |
g |
= |
Gravitational acceleration |
L |
= |
Characteristic dimension of object |
rho |
= |
Density of object |
rho_f |
= |
Density of surrounding fluid |
V |
= |
Velocity |
