The Cross-Sectional Area of a fuel injector in aircraft design refers to the area of the injector opening through which fuel is delivered. It’s an important parameter for understanding the flow of fuel. The formula for the cross-sectional area (A) of a fuel injector can be defined as:
- A is the cross-sectional area of the injector opening (in square meters, m²).
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- V is the velocity ofthe air entering the engine (in meters per second, m/s).
