The cross-sectional area (A) of low bypass turbofan engines in aircraft design is a measure of the area through which air flows. This area can be calculated using the following formula:
– A is the cross-sectional area (in square meters, m²).
– ṁ (pronounced “m-dot”) is the mass flow rate of air (in kilograms per second, kg/s).
– ρ (rho) is the air density (in kilograms per cubic meter, kg/m³).
– V is the velocity of the air (in meters per second, m/s).
