Textbook in PDF format Because of the part played by rotating machinery in the modern world, and the sophistication of the mathematical analyses required in the design of many machines, a study of rotating machines forms an important part of many undergraduate mechanical engineering courses, and is the central theme of many postgraduate studies. Furthermore, a detailed understanding is usually required by personnel employed in research, design, maintenance, and other areas of industry. The aim of this book is partly to review the general principles of operation of rotating machinery, thus satisfying the requirements of the undergraduate, but mainly to guide the graduate who continues to work with rotating machines in gaining a deeper understanding of the subject. The book should be particularly useful as a specialist reference text for personnel employed in industry
