In aircraft design, the velocity of the fuel system refers to the speed at which fuel flows through the fuel system components, such as pipes or fuel lines. It is an important parameter for ensuring efficient fuel delivery to the engines. The formula to calculate the velocity of the fuel system is:
- V is the velocity of the Fuel entering the engine (in meters per second, m/s).
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- A is the cross-sectional area through which Fuel enters (in square meters, m²).
