In aircraft design and engineering, the “velocity of outlet air” refers to the speed at which air exits an aircraft’s engine or a specific component of the engine, such as a turbine or exhaust nozzle. This parameter is important for understanding and optimizing engine performance.
Formula for Velocity of Outlet Air:The formula to calculate the velocity of outlet air is similar to the formula for inlet air velocity:
- Velocity (V) is the velocity of the outlet air, typically measured in meters per second (m/s).
- Mass Flow Rate (ṁ) is the rate at which mass exits the engine, measured in kilograms per second (kg/s).
- Density (ρ) is the density of the outlet air, typically measured in kilograms per cubic meter (kg/m³).
- Cross-Sectional Area (A) represents the area through which the air flows, measured in square meters (m²).
