3Objective: 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 toincrease the efficiency of the wheel.decrease the cost of the wheel, andincrease the reliability of the system.DDevelopment of various utility devices using Hydel Power other than the Electric power.IImprovisation of Mangal Turbine
4HHISTORYThe 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.
