The cross-sectional area (A) of a GE CF34 or any gas turbine engine in aircraft design is a measure of the opening or inlet through which air flows into the engine. The cross-sectional area is typically defined as the area of the engine’s inlet or the section where air enters the engine.
– A is the cross-sectional area through which the air is flowing (in square meters, m²).
– V is the velocity of the airflow (in meters per second, m/s).
– ṁ is the mass flow rate (in kilograms per second, kg/s).
– ρ is the air density (in kilograms per cubic meter, kg/m³).
