The density of the air entering an inverted 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).
