The fuel savings represents the percentage reduction in fuel consumption achieved through oxygen enrichment. It is calculated as the difference between baseline and enriched fuel consumption divided by the baseline, expressed as a percentage.

\begin{equation}\label{eq:o2-enrichment-fuel-savings} FS = \frac{FC_{base} - FC_{enriched}}{FC_{base}} \cdot 100\end{equation}

Symbols

\(FS\)	Fuel savings with O2 enrichment \([\unit{ \percent}]\)
\(FC_{base}\)	Baseline fuel consumption \([\unit{ \mega\btu\per\hour}]\)
\(FC_{enriched}\)	Fuel consumption with O2 enrichment \([\unit{ \mega\btu\per\hour}]\)
\(100\)	Conversion factor to percentage \([\unit{ \unitless}]\)
