Water Well and pump Engineering

This book presents a comprehensive treatment of the theory and practice of water wells and pumps for irrigation and water supply. This book comprises three parts. Parts I provides the technology for the design, construction, operation and maintenance of water wells for irrigation and water supply. Part II presents the application of electric motors and diesel engines in water pumping. The treatment on pumps and pumping, including the application of non-conventional energy sources in pumping, is included in Part III. It also includes a comprehensive treatment on techno-economic evaluation of projects on wells and pumps. Each topic on wells and pumps has been discussed with the help of self-explanatory diagrams. A large number of solved examples have been included to facilitate the application of the principles to solve field problems. For additional practice, many unsolved problems along with answers have been appended with each chapter. Metric units of weights and measures have been used throughout the text. Tables, figures and articles are numbered chapterwise. A list of important references is given for each chapter to establish authority and to assist the student who may wish to verify or read more deeply into any particular area. Further than this, citations from the exceedingly voluminous literature are not attempted. Contents: Preface Part One: Wells for Irrigation and Water Supply 1.
