Abstract

For thousands of years human beings have used the power of flowing water for various activities. However, there are several other ways we can generate energy using the power of water. This paper tends to demonstrate by experiment that the best efficiency point of a centrifugal pump both in direct and reverse mode can be investigated and used to determine electricity generation in a micro hydro scheme to power rural areas that might not be connected to the national grid. Investigations were done to test and measure the fuel rate of consumption of the centrifugal pump running in pump mode. The results demonstrated that the efficiency is indirectly proportional to the fuel level. The pressure and velocity head were also determined. The maximum velocity of flow was 3 • 90 m s ⁄ at a pressure gauge of 39 pal. Investigations were also done by testing the centrifugal pump in the pump mode to determine its best efficiency point (BEP) which was71%. In the pump mode investigation, the measured parameters were flow rate (8 • 17 m 3 s ⁄ ), speed (3589 rpm), power output (129 • 91 Watts), power input (183 • 02 Watts) and velocity flow (3 • 90 m s ⁄ ). The investigation shows that for the generation of electricity the centrifugal pump can be used as an alternative to a turbine.
