The mass flow rate of an afterburner in aircraft design is related to the additional fuel injected into the exhaust stream to increase thrust. The mass flow rate of the afterburner (ṁ_ab) 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 Afterbury (in square meters, m²).
- V is the velocity of the Afterburner (in meters per second, m/s
