Caution: the gas rate value is quoted on the x-axis, the related network pressure is quoted on the y-axis (pressure value in
the combustion chamber is not included). To know the minimum pressure at the gas train inlet, necessary to get the reque-
sted gas rate, add the pressure value in the combustion chamber to the value read on the y-axis.
