Hagen-Poiseuille equation (2)
Input(s)
\(\boldsymbol{P}_{\boldsymbol{o}}\): Input Pressure (psi)
\(\boldsymbol{P}_{\boldsymbol{L}}\): Output Pressure (psi)
\(\mathrm{R}\): Radius \((\mathrm{ft})\)
w: Mass rate of Flow (lb/s)
\(\boldsymbol{\rho}\): Density (ppg)
L: Length (ft)
Output(s)
\(\boldsymbol{\mu}\): Viscosity \((\mathrm{cP})\)
Formula(s)
\[
\mu=\frac{\left(\mathrm{P}_{\mathrm{o}}-\mathrm{P}_{\mathrm{L}}\right) * \pi *\left(\mathrm{R}^{4}\right) * \rho}{8 * \mathrm{~W} * \mathrm{~L}}
\]
