In aircraft design and engineering, the “cross-sectional area of outlet air” refers to the area through which air exits an aircraft’s engine or a specific component of the engine, such as a turbine or exhaust nozzle. This parameter is crucial for understanding and optimizing engine performance.Formula for Cross-Sectional Area of Outlet Air:The formula to calculate the cross-sectional area of outlet air is similar to the formula for inlet air.
- Cross-Sectional Area (A) represents he area through which the air flows, typically measured in square meters (m²).
- 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).
- Outlet Air Velocity (V) is the speed at which the air exits the engine, typically measured in meters per second (m/s).
