With its engineer-tested procedures and thorough explanations, Centrifugal Compressors is an essential text for anyone engaged in implementing new technology in equipment design, identifying process problems, and optimizing equipment performance. This condensed book presents a step by step approach to preparing for, planning, executing, and analyzing tests of centrifugal compressors, with an emphasis on methods that can be conducted on-site and with an acknowledgement of the strengths and limitations of these methods. The book opens with an extensive and detailed section offering definitions of relevant terms, which are explained not only in words, but also with the equations used to determine their values. Other discussion topics include: Selection of instrumentation and identification of elements to be measured; Strategies for data collection and evaluation; Recommendations for when to schedule tests; Pre-test, in-test, and post-test considerations (equipment, safety, process, environmental); and Computation and interpretation of results, including guidelines for field modifications and analysis of results.
