This book will be appreciated as a handy reference book by compressor design engineers and compressor maintenance engineers as well as engineering students. As its title suggests, this book covers the full spectrum of information needed for an individual to select, operate, test and maintain axial or centrifugal compressors. It includes some basic aerodynamic theory to provide the user with the "how's" and "why's" of compressor design. Maintenance Engineers especially will appreciate the troubleshooting guidelines offered. The many example problems and the reference data such as gas properties and flow meter calculations will enable easy analysis of compressor performance in practice. A computer program is also offered which will enhance the value of the book and the years of expertise and experience therein.M. Theodore Gresh has been with the Elliot Company in Jeannette, Pennsylvania, since 1975, initially working on the mechanical and aerodynamic design and application of centrifugal compressors.
