Operating Characteristics of Turbocompressors
This text is not meant to duplicate the hundreds of other texts on compressor operation. Instead, its intended function is to synthesize and to address the needs of our target audience. As authors, we believe the operating characteristics of turbocompressors must be understood if safe and efficient operation is to be obtained.
The relationship between the inlet volume and the discharge pressure of a centrifugal compressor is called its characteristic curve; the terms characteristic curve and performance curve are used interchangeably for these curve-shaped representations (Fig. 3.1).
