Micro Hydel Turbine Prof. P. M. V. Subbarao Prof.Sanjeev Jain Prof.Santosh Satya Anand Krishnan Plappally IIT, DELHI
Mangal Turbine on River Sajnam, Bhailoni Lod Village Lalitpur Dist. Dr S K Saha,IAS Reviewing the Mangal water Wheel
Objective: VVisits to the different Sites in Gharwal area and eEstimation of hydro potential of these sites. MMeasurement of geometry and performance of the existing water wheels. DDevelopment of improved design of water wheel to increase the efficiency of the wheel. decrease the cost of the wheel, and increase the reliability of the system. DDevelopment of various utility devices using Hydel Power other than the Electric power. IImprovisation of Mangal Turbine
HHISTORY The first reference to its use dates back to about 4000 B.C., where, in a poem by an early Greek writer, Antipater, it tells about the freedom from the toil of young women who operated small handmills to grind corn. AAs early as the first century, waterwheels of the vertical design were replacing the horizontal waterwheel. An early horizontal-wheeled watermill used for grinding grain in Greece was the called Norse Mill. In Syria, the watermills were called "noriahs". They were used for running mills to process cotton into cloth. OThe three distinct types of water mills, The simplest and probably the earliest was a vertical wheel with paddles on which the force of the stream acted. Next was the horizontal wheel used for driving a millstone through a vertical shaft attached directly to the wheel. Third was the geared mill driven by a vertical waterwheel with a horizontal shaft.
Applications: Grinding Grains Rural Electrification Irrigation De Husking Cotton combing Rice Huller Other Agriculture related machines
