 **Air density**
 The air density is calculated using the temperature and the air pressure, as stated in the diagram above. For this calculation the formula $\rho = \frac{(P \cdot M)}{R \cdot T}$ is used. The arguments for this formula are listed in the table below. In case no air pressure is given, the default value $1.2401 \frac{kg}{m^3}$ is returned, which corresponds to the air density at sea level at 20° Celsius.
