Temperature Adjustment Formula

The temperature adjustment converts actual volumetric flow at operating temperature to standard conditions (60°F or 520°R). Gas volume is inversely proportional to the square root of absolute temperature.

\begin{equation}\label{eq:flow-calculations-convert-temperature} T_{gas} = T_{gas,F} + 459.67\end{equation}

\begin{equation}\label{eq:flow-calculations-temperature-adj} f_T = \sqrt{\frac{T_{std}}{T_{gas}}}\end{equation}
