Hagen Poiseuille equation (1)
Input(s)
\(P_{o}\): Input Pressure (psi)
\(P_{L}\): Output Pressure (psi)
\(\mathrm{R}\): Radius (ft)
w: Mass rate of Flow (lb/s)
\(\rho\): Density \((\mathrm{ppg})\)
L: Length (ft)
Output(s)
\(\mu\): Viscosity (cP)
Formula(s)
\[
\mu=\frac{\left(P_{o}-P_{L}\right) * \pi *\left(R^{4}\right) * \rho}{8 * w * L}
\]
