The mass flow rate (ṁ) of a GE Honda HF120 or any gas turbine engine in aircraft design can be calculated using the same fundamental formula as mentioned previously:
– 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).
