The specific heat of air varies with temperature according to an empirical linear relationship. This accounts for the temperature-dependent thermodynamic properties of air. The base specific heat and temperature coefficient are referenced from physics::us::kSpecificHeatAirBase and physics::us::kSpecificHeatAirCoeff.
\begin{equation}\label{eq:o2-enrichment-air-specific-heat} C_{p,air} = C_{p,base} + k_{temp} \cdot T_{air}\end{equation}
| \(C_{p,air}\) | Air specific heat \([\unit{ \btu\per\pound\per\degreeFahrenheit}]\) |
| \(C_{p,base}\) | Base specific heat of air (0.017828518) - see physics::us::kSpecificHeatAirBase \([\unit{ \btu\per\pound\per\degreeFahrenheit}]\) |
| \(k_{temp}\) | Temperature coefficient (0.000002556) - see physics::us::kSpecificHeatAirCoeff \([\unit{ \btu\per\pound\per\degreeFahrenheit\per\degreeFahrenheit}]\) |
| \(T_{air}\) | Combustion air preheat temperature \([\unit{ \degreeFahrenheit}]\) |
