In aircraft design, the mass flow rate of the fuel system refers to the amount of fuel flowing through the aircraft’s fuel system per unit of time. It is a critical parameter in engine performance and fuel efficiency calculations. The formula to calculate the mass flow rate of the fuel system is as follows:.
- 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).
- V is the velocity of the Fuel entering the engine (in meters per second, m/s).
