Cross-flow hydraulic turbine becomes viable in low head and small water flow rate. Because of its simple in structure and ease of manufacturing, it is familiar in scheme of small hydro-power plant. Here in this book, flow pattern, hydrological data of Specific River being studied, penstock design and it's material, design of all turbine parameters, design and selection of power transmission devices, generator selection, total energy production, Computational fluid dynamics and economic analysis of cross flow turbine were briefly described in this book.
