Hydraulic Machines Turbines and PumpsThis Second Edition of Hydraulic Machines is devoted to the operating principles, design, and performance characteristics of hydraulic machines used in electric power plants, municipal facilities, construction works, hydraulic engineering, industry, and agriculture. You'll learn how to select hydraulic turbines, pumps, and reversible pump-turbines, analyze their efficiency, and maintain them for peak performance. The book emphasizes the types and construction of the machinery, especially the mechanical aspects of their operation, including head, discharge, power, efficiency, cavitation factors, reliability, and maintenance. Performance characteristics and recommendations for their use are provided, in addition to installation and operation guidelines. Data on the characteristics and parameters is presented for easy reference. Numerical examples promote a better understanding of the methods and relationships discussed, and excellent technical drawings help illustrate the design of components and workings of the machinery. |
