ABSTRACT
This paper presents a design of a hydroelectric scheme specially proposed for low head applications. After carefully studying the hydrology and geographical conditions of the site, turbine is designed for the heads of 3 to 10 meters obtainable from streams and irrigation channels. The low efficiency in already existing hydroelectric scheme used is addressed and compared with the existing scheme. Using the standard equations, trash rack, penstock and turbine is designed thus keeping the power losses as low as 4%. Hence finally an electrical power of 25kW is produced, suitable to run a farm in villages where electricity supply is not available and where cost of transmission and distribution is high. The location where it has been installed and tested is village Kandar, Tehsil Mathra, Peshawar. The present project is compared with the existing and is much cost-effective and highly efficient.
