In aircraft design, the density (ρ) at the inlet of a pressure injection carburetor can be calculated using the ideal gas law:
– ρ is the density of the air (in kilograms per cubic meter, kg/m³)
– P is the pressure of the air (in pascals, Pa)
– R is the specific gas constant for air (approximately 287.05 J/(kg·K))
– T is the temperature of the air (in kelvin, K)
