The consumption of energy taking place in pumping systems accounts for approximately twenty per cent of the world's electrical energy demand. Moreover, the operational cost of pumping machinery tar outweighs their capital cost. Accordingly, engineers strive for optimum equipment performance for achieving economic operation, and a thorough understanding of the components and operating principles of these machines will provide an opportunity to dramatically reduce energy, as well as operational and maintenance costs. Reducing energy consumption will also complement the current thrust towards protecting our environment. This book is intended to be a basic reference on theoretical foundation and applications of various types of pumping machinery. In view of the great importance of pumps and compressors in almost every engineering system, this book presents the fundamental concepts underlying the flow processes taking place in these machines and the transformation of mechanical energy into fluid power. Special emphasis is given to basic theoretical formulation and design considerations of pumps and compressors in addition to improving problem-solving skills. This is achieved through the presentation of solved examples of applied nature using analytical means and/or basic engineering practices. The book consists of ten chapters covering two main themes: the first smoothly introduces the essential terminology, basic principles, design considerations, and operational-type problems in pumping machinery. This part is supported by a good number of worked examples plus problems at the end of each chapter for the benefit of senior undergraduate students and junior engineers. This is considered a key feature of this book because other books in this area rarely provide enough worked problems and exercises. The second theme focuses on advanced topic such as two-phase flow pumping systems targeting practicing field engineers and introductory research scientists.
