In aircraft design, fuel density (ρ) represents the mass of fuel per unit volume. It’s an important parameter because it allows for the conversion between fuel volume and fuel mass. The formula and SI unit for fuel density are as follows:Formula:
The formula for calculating fuel density (ρ) is straightforward:
- Fuel Density (ρ) is the density of the fuel in kilograms per cubic meter (kg/m³).
- Mass (m) is the mass of the fuel in kilograms (kg).
- Volume (V) is the volume of the fuel in cubic meters (m³).
