Formula 4.110
Wellbore pressure loss due to friction during hydraulic fracturing (turbulence flow)
Input(s)
$\rho$: Liquid Density (lb/gal)
v: Average Velocity $(\mathrm{ft} / \mathrm{s})$
$f$: Fanning Friction Factor (dimensionless)
L: Pipe Length $(\mathrm{ft})$
$d$: Inner Diameter of Pipe (in.)
Output(s)
$\Delta P_{f}$: Pressure Loss in the wellbore Sourced by Frictions during Hydraulic Fracturing (psi)
Formula(s)
$$ \Delta P_{f}=\frac{f \cdot L \cdot \rho \cdot v^{2}}{25.80 \cdot d} $$
