The cross-sectional area (A) in the context of a GE Honda HF120 or any gas turbine engine represents the area through which air or another working fluid enters the engine. The specific formula for calculating this area depends on the engine’s design and geometry.
– 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).
