The mass flow rate of an aircraft engine, such as a CFM (CFM International) engine, represents the amount of air that passes through the engine per unit of time. It is a critical parameter for engine performance. The formula for mass flow rate (ṁ) is:
– ṁ is the mass flow rate (in kilograms per second, kg/s).
– ρ (rho) is the air density (in kilograms per cubic meter, kg/m³).
– A is the cross-sectional area through which air flows (in square meters, m²).
– V is the velocity of the air (in meters per second, m/s).
