The velocity of a nozzle in aircraft design represents the speed at which a fluid or substance exits the nozzle. The formula to calculate the velocity of the nozzle (V) is as follows:
- V = Velocity of the nozzle (in meters per second, m/s)
- ṁ = Mass flow rate of the fluid or substance passing through the nozzle (in kilograms per second, kg/s)
- ρ = Density of the fluid or substance passing through the nozzle (in kilograms per cubic meter, kg/m³)
- A = Cross-sectional area of the nozzle (in square meters, m²)
