The cross-sectional area of the exhaust 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_exhaust) is as follows:
- A = Cross-sectional area of the Exhaust (in square meters, m²)
- ṁ = Mass flow rate of the fluid (in kilograms per second, kg/s)
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- V = Inlet velocity of the fluid (in meters per second, m/s)
