Description: This book offers a comprehensive reference work for engineers, researchers, and students involved in the design, testing, and improvement of wind-driven water pumps. By providing a thorough treatment of the factors which affect the success of pump performance, combined with the fundamentals of machine design, this book distinguishes itself from a simple design manual, and therefore allows the reader to determine the most efficient wind-pump configuration based on specific needs and resources.

The latest international developments in wind-driven water pumping technologies are discussed, including a survey of the advantages and disadvantages of the alternative configurations to the more "standard" designs. In a field where technical information is limited, this book will serve as a valuable resource for the wind-engineering community.
Notes: Includes bibliographical references (p. 265-272) and indexes.
