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.
