Web2 feb. 2024 · The resistance offered by a fluid, like air and water, ... When it takes place in water, it is known as hydrodynamic drag. The following equation gives the magnitude of the drag force. \[F_D = \frac{1}{2} C \rho_f A v^2\] Where, C is the drag coefficient, which is dimensionless with values depending upon the shape of the object. Web17 nov. 2016 · In Engineering the total drag from both sources is modelled by a single equation : F = 1 2 C d ρ A v 2. where ρ is fluid density, v is speed through the fluid, A is an appropriate area and C d is the relevant drag coefficient, which depends on the shape of the object relative to the direction of flow. As you can see, viscosity does not enter ...
