Aerodynamics For The User
by: M. Theodore Gresh

This 224 page book provides complete information on the selection, operation, testing, and aerodynamic maintenance of axial and centrifugal compressors. Coverage includes design information, gas properties data, flow meter calculation, and troubleshooting guidelines.

Design parameters are covered to provide the user with the basic "how" and "why" of compressor design. Maintenance engineers will particularly appreciate the troubleshooting guidelines provided. The many example problems along with the reference data furnished will provide easy analysis of compressor performance.
