The Mass Flow Rate of Exhaust Nozzle (ṁ_exhaust) in aircraft design represents the rate at which exhaust gases exit the propulsion system’s nozzle. It’s a critical parameter in understanding the performance of jet engines.
The formula for mass flow rate of exhaust gases is given by:
- ṁ_exhaust is the mass flow rate in kilograms per second (kg/s).
- ρ (rho) is the density of the exhaust gases in kilograms per cubic meter (kg/m³).
- A is the cross-sectional area of the nozzle’s exit in square meters (m²).
- V is the velocity of the exhaust gases at the nozzle exit in meters per second (m/s).
