When multiple identical leak points are present (e.g., several identical fittings of the same worn type), the total leak rate is the per-orifice flow rate multiplied by the number of orifices. This aggregation is appropriate when all orifices share the same supply pressure, temperature, diameter, and discharge coefficient.

\begin{equation}\label{eq:orifice-method-total-leak} Q_{leak} = Q_{scfm} \cdot n \end{equation}

Symbols

\(Q_{leak}\)	Total volumetric leak flow rate for all orifices \([\unit{ \scfm}]\)
\(Q_{scfm}\)	Volumetric flow rate per orifice \([\unit{ \scfm}]\)
\(n\)	Number of identical orifice leak points \([\unit{ \unitless}]\)
