Fanning's friction factor (turbulent flow)

Input(s)

D: Diameter $(\mathrm{ft})$

v: Velocity of Fluid ( $\mathrm{ft} / \mathrm{s})$

$\rho$: Density of Fluid $(\mathrm{g} / \mathrm{cc})$

$\mu$: Visocosity of Fluid $(\mathrm{cP})$

Output(s)

f: Friction Factor (dimensionless)

Formula(s)

$$ \mathrm{f}=\frac{0.0791 * \mu^{0.25}}{(\mathrm{D} * \mathrm{v} * \rho)^{0.25}} $$
