airdensity
Airdensity, more commonly written as air density, is the mass of air per unit volume. It is typically expressed in kilograms per cubic meter (kg/m^3) and is a key property of the Earth's atmosphere that influences aerodynamics, weather, and ventilation. Air density depends on the state of the air, including its pressure, temperature, humidity, and chemical composition.
Under the ideal gas approximation, density is described by the equation rho = p / (R_specific * T), where
Standard reference values place sea-level dry air density at about 1.225 kg/m^3 at 15°C (288.15 K) and
