Abstract

Evaluation of power potential is the scheme forms a primary step in the planning of a hydroelectric project. It relates to the assessments to be made of probable quantum of electrical energy which can be expected to generate at the site based on characteristic features of quantity of water flow and head available at the site at different periods of a year. This assessment forms the basis for the planning the layout and design of the hydropower scheme and estimation of the cost and evaluation of the financial aspect of the scheme. Cavitations in water turbine runner casing induces vibrations, damage to the materials, unendurable noise, losses in the efficiency and alteration in flow pattern and finally the power loss. Hence, hydraulic machineries have to be designed entirely free from cavitation.
