The velocity of the exhaust nozzle in aircraft design represents the speed at which exhaust gases exit the engine’s nozzle. It is a critical parameter in engine performance analysis. The formula to calculate the velocity of the exhaust nozzle (V_nozzle) is as follows:
- V = Velocity of the exhaust nozzle (in meters per second, m/s)
- 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)
- A = Cross-sectional area of the exhaust nozzle (in square meters, m²)
