The velocity of a jet engine in aircraft design represents the speed at which air enters the engine. It’s a fundamental parameter in engine performance analysis. The formula to calculate the velocity of a jet engine’s inlet air (V_inlet) is as follows:
- V = Velocity of the jet engine’s inlet air (in meters per second, m/s)
- ṁ = Mass flow rate of the jet 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)
