The cross-sectional area (A) of high bypass turbofan engines in aircraft design represents the area through which air flows. It is essential for calculating various parameters in engine design. The formula for the cross-sectional area is:
– 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 air (in meters per second, m/s).
