In aircraft design, the density of air (ρ) is an important parameter as it affects various aspects of aircraft performance, such as lift, drag, engine performance, and more. The density of air can be calculated using the ideal gas law.
- – ρ (rho) = Air Density (in kilograms per cubic meter, kg/m³)
- – P = Pressure of the air (in pascals, Pa)
- – R = Specific Gas Constant for dry air (in joules per kilogram-kelvin, J/(kg·K))
- – T = Temperature of the air (in kelvin, K)
