# Pressure loss due to perforations during hydraulic fracturing - 2

## Input(s)

\(\rho\): Specific Gravity (lb/gal)

\(q\) : Real Flowing Rate \((\mathrm{gal} / \mathrm{min})\)

\(A_{2}\) : Fracture Area in time "t" \(\left(\right.\) in \(\left.^{2}\right)\)

## Output(s)

\(\Delta P_{p}\): Pressure Loss in Sourced by Perforations during Hydraulic Fracturing (psi)

## Formula(s)

\[
\Delta P_{p}=\frac{\rho \cdot q^{2}}{8090 \cdot A_{2}^{2}}
\]
