  • Understanding centrifugal compressor performance

    Centrifugal compressors have performance curves similar to pumps The major difference is that a compressor moves gas which is compressible, while the pump moves liquid that is not compressible The compressor curve flow term is always based on inlet conditions Consequently, inlet gas density influences volumetric flow
