Drag coefficient
Input(s)
\(\rho\): Mass Density of the Fluid \(\left(\mathrm{kg} / \mathrm{m}^{3}\right)\)
\(\mathrm{u}\): Flow Speed of the Object Relative to the Fluid \((\mathrm{m} / \mathrm{s})\)
\(\boldsymbol{F}_{\boldsymbol{d}}\): Drag Force \((\mathrm{N})\)
A: Cross Sectional Area \(\left(\mathrm{m}^{2}\right)\)
Output(s)
\(\boldsymbol{c}_{\boldsymbol{d}}\): Drag Coefficient (dimensionless)
Formula(s)
\[
\mathrm{c}_{\mathrm{d}}=\frac{2 * \mathrm{~F}_{\mathrm{d}}}{\rho * \mathrm{u}^{2} * \mathrm{~A}}
\]
