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 |
