In aircraft design and engineering, the “flow rate” in an axial flow compressor refers to the rate at which air is drawn into and compressed by the compressor. This flow rate is a crucial parameter for assessing the performance and behavior of the compressor and the overall operation of the aircraft engine.
The formula for calculating the flow rate (ṁ) in an axial flow compressor can be defined as:
- 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.
