Abstract
Theoretical investigation has shown a simple reaction water turbine would perform better when it spins faster. And for the simple reaction turbine water turbine to spin faster under constant water head, its diameter should be smaller. This paper reports on a performance analysis based on the experimental data collected from different performance tests carried on two simple reaction water turbine prototypes. Two new designs of simple reaction water turbines and their manufacturing methods are reported. The two turbines under investigation have different rotor diameters Φ 0.243 m and Φ 0.122 m. In case of the simple reaction water turbine the water enters into the turbine axially and exits tangentially through nozzles located on the outer periphery of the turbine. Further this paper will discuss the performance characteristics of stationary turbine i.e. zero power produced and performance characteristics of turbine producing power. It was found that rotor diameter affects the maximum rotational speed of the simple reaction turbine for constant supply head. It was also found that faster the turbine spins its performance improves. The two turbines were tested between supply head range of 1 m to 4 m.

Most of the low head hydro turbines are large and bulky to the air drag the mechanical power loss contains the power loss due to friction in the V-ring lip seal. It was observed from the power loss tests that the power loss due to V-ring lip seal sharply increased at higher rotational speeds
Summary
The role of renewable energy in tomorrow’s world is of great significance for the global environmental stability. Wind and flowing or stored hydro (water) are considered the most common renewable energy sources for power generation. Out of these three renewable energy resources, the advantage of hydro energy is that it can continuously supply energy and can serve as a base power. The world hydro power scenario show that the technically exploitable potential of hydro energy is about 14,000 TWh year and the economically exploitable potential is about 8000 TWh year, where as the present global hydro power generation stands at 2800 TWh/year [2,4]. Hydropower is a good example of renewable energy; its present use and potential application to future power generation cannot be underestimated.
