Power Generation by Screw Type Turbine

Abstract

India has more than 600 rivers. It is difficult to construct dams on any type of river. The farmer's residency is on the basis of river. By power derived from the potential energy and running water production of electrical power through the use of the gravitational force and electricity generated is called as hydroelectricity. Therefore the hydro-power plant is used in this type of conditions. Hydro-power plant has an important source which deals with the water flow. Hydro screw is suitable for a low head discharged which does not guide to draft a tube. Geometrical dimension of one screw blade is of the angle of 50 0 .the turbine slope variable are 20 0 ,30 0 and 40 0. According to experimental data, the turbine's maximum efficiency is 83%. This has an important property in which the inclination of angle is increased which results in the large amount of the flowing water and this power plant is environment friendly. This power plant was used for small rivers.
