Perforation friction pressure
Input(s)
Q: Flow Rate \(\left(\mathrm{m}^{3} / \mathrm{min}\right)\)
\(\rho\) : Fluid Density \((\mathrm{kg} / \mathrm{L})\)
\(\mathrm{n}\) : Number of Perforations (unitless)
\(D_{p}\): Diameter of Perforation \((\mathrm{cm})\)
C: Perforation Coefficient (0.6-1.0) (unitless)
Output(s)
\(\Delta P_{p f}\): Perforation Friction Pressure (MPa)
Formula(s)
\[
\Delta P_{p f}=22.335 * \frac{Q^{2} * \rho}{n^{2} * C^{2} * D_{p}^{4}}
\]
