Frictional pressure drop (Economides and Nolte)
Input(s)
q: Injection Rate (bbl/min)
\(\mu\) : Fluid Viscosity \((\mathrm{cP})\)
\(\rho\): Density of Fluid \((\mathrm{g} / \mathrm{cc})\)
D: Tubing Diameter (in.)
L: Tubing Length (ft)
Output(s)
\(\Delta P_{f:} \quad\) Frictional Pressure Drop (psi)
Formula(s)
\[
\Delta P_{f}=518 * \rho^{0.79} * q^{1.79} * \mu^{0.207} * \frac{L}{1000 * D^{4.79}}
\]
