Pressure loss due to perforations during hydraulic fracturing
Input(s)
\(\rho\): Specific Gravity \(\left(\mathrm{lb} / \mathrm{ft}^{3}\right)\)
\(q\) : Real Flowing Rate \(\left(\mathrm{ft}^{3} / \mathrm{s}\right)\)
\(g_{c}\): Unit Conversion Factor \(\left(32.2(\mathrm{lb} \cdot \mathrm{ft}) /\left(\mathrm{lbf} \mathrm{s}^{2}\right)\right.\)
\(A_{2}\) : Fracture Area in time " \(\mathrm{t}\) " \(\left(\mathrm{ft}^{2}\right)\)
Output(s)
\(\Delta P_{p}\): Pressure Loss in Sourced by Perforations during Hydraulic Fracturing (psi)
Formula(s)
\[
\Delta P_{p}=\frac{\rho \cdot q^{2}}{1.345 \cdot g_{c} \cdot A_{2}^{2}}
\]
