In aircraft design and engineering, the flow rate in an axial or centrifugal compressor refers to the rate at which air is drawn into and compressed by the compressor.
- ṁ is the flow rate, typically measured in kilograms per second (kg/s) or other mass flow rate units.
- ρ (rho) is the density of the air, typically measured in kilograms per cubic meter (kg/m³) or other density units.A is the cross-sectional area through which the air flows, typically measured in square meters (m²) or other area units.
- V is the velocity of the air, typically measured in meters per second (m/s) or other velocity units.
