Friction factor in flow through conduits
Input(s)
D: Diameter of Conduit ( \(\mathrm{ft}\) )
L: Length of Conduit (ft)
v: Fluid Velocity (ft/s)
\(\boldsymbol{P}_{\boldsymbol{o}}\): Inlet Pressure (psi)
\(\boldsymbol{P}_{\boldsymbol{L}}\): Outlet Pressure (psi)
\(\rho\): Density \((\mathrm{g} / \mathrm{cc})\)
Output(s)
f: Friction Factor (dimensionless)
Formula(s)
\[
\mathrm{f}=\frac{0.25 * \mathrm{D} *\left(\mathrm{P}_{\mathrm{o}}-\mathrm{P}_{\mathrm{L}}\right)}{0.5 * \mathrm{~L} * \rho *\left(\mathrm{v}^{2}\right)}
\]
