Friction factor in flow around submerged objects
Input(s)
g: Gravitational Acceleration \(\left(\mathrm{ft} / \mathrm{s}^{2}\right)\)
v: Fluid Velocity (ft/s)
D: Diameter \((\mathrm{ft})\)
\(\rho\): Fluid Density \((\mathrm{g} / \mathrm{cc})\)
\(\rho_{s p h}\): Density of Sphere \((\mathrm{g} / \mathrm{cc})\)
Output(s)
f: Friction Factor (dimensionless)
Formula(s)
\[
\mathrm{f}=\left(\frac{4 * \mathrm{~g} * \mathrm{D}}{3 * \mathrm{v}^{2}}\right) *\left(\frac{\rho_{\mathrm{sph}}-\rho}{\rho}\right)
\]
