The velocity of a turbojet engine in aircraft design represents the speed at which air enters the engine. It is a fundamental parameter for engine performance analysis. The formula to calculate the velocity of the air entering the turbojet engine (V_inlet) is as follows:
- V = Velocity of the air entering the turbojet engine (in meters per second, m/s)
- ṁ = Mass flow rate of the engine (in kilograms per second, kg/s)
- ρ = Density of the air ingested by the engine (in kilograms per cubic meter, kg/m³)
- A Cross-sectional area of the engine inlet (in square meters, m²
