The heat loss is calculated by multiplying the gas flow rate, density, specific heat, temperature rise, and correction factor. The factor of 60 converts from standard cubic feet per minute to standard cubic feet per hour.

\begin{equation}\label{eq:gas-cooling-heat-loss} Q_\text{cool} = FR \cdot 60 \cdot \rho_{g,lb/ft^3} \cdot SH \cdot \Delta T \cdot CF\end{equation}
