  • Synopsis
    Developed from Intermediate Technology (now Practical Action) experience in Sudan, this handbook describes the development and testing of the water current turbine as a simple and inexpensive means of lifting water for irrigation purposes. With detailed technical information on the technology, this manual also includes an economic assessment of its cost-effectiveness compared with other pumping technologies. This book is designed for the use of engineers and development workers who may be interested in trying this technology
