Each receiver capacity is divided by the existing implementation conversion factor, then the converted receiver volumes are summed.

\begin{equation}\label{eq:air-system-capacity-receiver-volume} V_{receiver,j} = \frac{G_j}{k_{gal}} \end{equation}

\begin{equation}\label{eq:air-system-capacity-total-receiver-volume} V_{receiver,total} = \sum_j V_{receiver,j} \end{equation}

Symbols

\(V_{receiver,j}\)	Converted volume for receiver j \([\unit{ \cubicFoot}]\)
\(G_j\)	Entered capacity for receiver j \([\unit{ \gallon}]\)
\(k_{gal}\)	Gallons per cubic foot conversion factor (7.480515625) \([\unit{ \gallon\per\cubicFoot}]\)
\(V_{receiver,total}\)	Total converted receiver volume \([\unit{ \cubicFoot}]\)
