To calculate the enthalpy of air (E):
\[ E = 1.007 \cdot T - 0.026 \]
Where:
The enthalpy of air is defined as the total energy per unit of mass of an isolated area of air at a constant temperature. It is a measure of the heat content of the air and is used in various applications such as heating, ventilation, and air conditioning (HVAC) systems to assess the energy efficiency and thermal comfort of indoor environments.
