The mass flow rate (ṁ) of high bypass turbofan engines in aircraft design represents the amount of air passing through the engine per unit of time. It can be calculated using the following formula:
– 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).
– 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).
