What are specifications of axial flow compressors?

Axial flow compressors are characterized by their design, which allows air to flow parallel to the axis of rotation through a series of rotating and stationary blades. Key specifications include the pressure ratio, which indicates the increase in pressure from inlet to outlet, typically ranging from 2:1 to 10:1; efficiency levels, often between 85% to 90%; and airflow capacity, measured in cubic feet per minute (CFM) or kilograms per second (kg/s). Additionally, they are known for their compact design and high rotational speeds, typically operating at several thousand RPM, making them suitable for applications in jet engines and gas turbines.
