Abstract
Archimedes screw is one of the biggest innovations that the human mankind has ever experienced. From the day of its innovation AST has upgraded the lives of the people. Various studies have been done considering various parameters and the results shows that the maximum efficiency is recorded in between 20 and 25 degrees, but the accurate angle hasn’t been shown in any of the study. The experimentation study reveals that the maximum efficiency of 74.27% is recorded at 22 degrees with flow rate of 1 l/s and load of 0.9 kg. Maximum output power of 0.00577 kW was recorded at load 0.9 kg and Flow rate 4 l/s at 25-degree tilt angle. maximum speed of 141 RPM was recorded at load 0.5 kg at Tilt angle of 25 degree and at 4 l/s of flow rate. The results show the feasibility of AST to be installed at low head sites at low tilt angle and at heavy loads.
