The mass flow rate (ṁ) of an LM2500 or any gas turbine engine can be calculated using the following formula:
– ṁ is the mass flow rate (in kilograms per second, kg/s).
– ρ is the air density (in kilograms per cubic meter, kg/m³).
– A is the cross-sectional area through which air is flowing (in square meters, m²).
– V is the velocity of the air (in meters per second, m/s).
