The density of the air entering an inline piston engine in aircraft design can be calculated using the ideal gas law. The formula for density (ρ) can be defined as
– ρ is the air density (in kilograms per cubic meter, kg/m³).
– P is the pressure of the air (in pascals, Pa).
– R is the specific gas constant (in joules per kilogram per kelvin, J/(kg·K)).
– T is the temperature of the air (in kelvin, K).
