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)

$$ \Delta P_{f}=518 * \rho^{0.79} * q^{1.79} * \mu^{0.207} * \frac{L}{1000 * D^{4.79}} $$
