The second edition of this well-received book, continues to present the operating principles and working aspects of thermal and hydraulic machines. First, it covers the laws and the essential principles of thermodynamics that form the basis on which thermal machines operate. It subsequently presents the principles, construction details and the methods of control of hydraulic and thermal machines. The coverage of thermal machines includes steam turbines, gas turbines, IC engines, and reciprocating and centrifugal compressors. The coverage of hydraulic machines includes hydraulic turbines, reciprocating pumps and centrifugal pumps. The classification, construction and efficiency of these machines have been discussed with plenty of diagrams and worked problems. This will help the readers understand easily the underlying principles. This new edition includes substantially updated chapters and also introduces additional text as per the syllabus requirement. The book is intended for the undergraduate engineering students pursuing courses in mechanical, electrical and civil branches. KEY FEATURES : Provides succinct coverage of all operating aspects of thermal and hydraulic machines. Includes a large number of worked problems at the end of each chapter to help students achieve a sound understanding of the subject matter. Gives objective type questions with explanatory answers to assist students in preparing for competitive examinations.
Thermal and Hydraulic Machines has been introduced as a core subject for Electrical, Electronics, Mechanical and students of other branches of engineering by various technical universities. The present book has been designed to meet the requirements of teachers and students for the above important subject. The book has been divided into following five units: 1. Thermodynamics and Vapour Power Cycles 2. Steam Turbine and Gas Turbine 3. Compressors and I.C. Engines 4. Hydraulics and Hydraulic Turbines 5. Hydraulic Pumps. The book has been written in simple language duly supplemented by solved numerical problems, diagrams and mathematical analysis. Suggestions and criticism for the improvement of the book are welcome with gratitude.
This first volume of the textbook Hydraulic and Thermal Machines introduces readers to all necessary fundamentals to understand and operate hydraulic and thermal machines. No prior knowledge in machinery is required. With an uncomplicated yet rigorous approach, it gradually guides bachelor students, with no prior knowledge in machines, from basic concepts such as dimensions and SI base and derived units, to more complex, mathematical and mechanical fundamentals of hydraulic machines, energy conversion processes, fluids, including real ones, as well as hydrostatics and hydrodynamics. In turn, the book gets into the basic structure and operating modes of pumps and turbines, ending up with the study of fluid dynamic transmission in hydraulic machines. Numerous examples are analyzed in detail, for a comprehensive understanding and effective learning, which will prepare readers to the second volume of this set.
Vibration of Hydraulic Machinery deals with the vibration problem which has significant influence on the safety and reliable operation of hydraulic machinery. It provides new achievements and the latest developments in these areas, even in the basic areas of this subject. The present book covers the fundamentals of mechanical vibration and rotordynamics as well as their main numerical models and analysis methods for the vibration prediction. The mechanical and hydraulic excitations to the vibration are analyzed, and the pressure fluctuations induced by the unsteady turbulent flow is predicted in order to obtain the unsteady loads. This book also discusses the loads, constraint conditions and the elastic and damping characters of the mechanical system, the structure dynamic analysis, the rotor dynamic analysis and the system instability of hydraulic machines, including the illustration of monitoring system for the instability and the vibration in hydraulic units. All the problems are necessary for vibration prediction of hydraulic machinery.
The favourable and warm reception,which the previous editions and reprints of this popular book has enjoyed all over India and abroad has been a matter of great satisfaction for me.
This comprehensive book is an earnest endeavour to apprise the readers with a thorough understanding of all important basic concepts and methods of fluid mechanics and hydraulic machines. The text is organised into sixteen chapters, out of which the first twelve chapters are more inclined towards imparting the conceptual aspects of fluids mechanics, while the remaining four chapters accentuate more on the details of hydraulic machines. The book is supplemented with solutions manual for instructors containing detailed solutions of all chapter-end unsolved problems. Primarily intended as a text for the undergraduate students of civil, mechanical, chemical and aeronautical engineering, this book will be of immense use to the postgraduate students of hydraulics engineering, water resources engineering, and fluids engineering. Key features • The book describes all concepts in easy-to-grasp language with diagrammatic representation and practical examples. • A variety of worked-out examples are included within the text, illustrating the wide applications of fluid mechanics. • Every chapter comprises summary that presents the main idea and relevant details of the topics discussed. • Almost all chapters incorporate objective type questions of previous years’ GATE examinations, along with their answers and in-depth explanations. • Previous years’ IES conventional questions are provided at the end of most of the chapters. • A set of theoretical questions and numerous unsolved numerical problems are provided at the chapter-end to help the students from practice pointof-view. • Every chapter consists of a section Suggested Reading comprising a list of publications that the students may refer for more detailed information.
