Heat Capacity of Air Formula

The heat capacity of air is calculated from the volumetric airflow rate converted to an hourly basis. An empirical factor of 0.0186 is applied to account for the specific heat of air at typical combustion conditions.

\begin{equation}\label{eq:air-heating-exhaust-heat-capacity-air} C_{air} = 0.0186 \cdot \dot{V}_{air} \cdot 60\end{equation}
