The cross-sectional area of the exhaust nozzle in aircraft design represents the area through which exhaust gases exit the engine’s nozzle. It is a critical parameter for understanding engine performance and emissions. The formula to calculate the cross-sectional area of the exhaust nozzle (A_nozzle) is as follows:
- A = Cross-sectional area of the exhaust nozzle (in square meters, m²)
- ṁ = Mass flow rate of the exhaust nozzle (in kilograms per second, kg/s)
- ρ = Density of the exhaust gases at the nozzle (in kilograms per cubic meter, kg/m³)
- V = Velocity of the exhaust gases at the nozzle (in meters per second, m/s)
