In aircraft design and engineering, “specific volume” is a property of a fluid (such as air) that represents the volume occupied by one unit of mass of that fluid. It’s essentially the reciprocal of density and provides information about how much space a given mass of the fluid occupies.
The formula for calculating specific volume (v) can be defined as:
- Specific Volume (v) is the specific volume of the fluid, typically measured in cubic meters per kilogram (m³/kg) or other volume per unit mass units.
- Volume (V) is the total volume of the fluid, typically measured in cubic meters (m³) or other volume units.
- Mass (m) is the mass of the fluid, typically measured in kilograms (kg) or other mass units.
