Development of a wind powered pump
Increase in global warming due to the increased emissions of greenhouse gases has become a major concern in the world. This has led to development in renewable energy systems, which are termed as clean energy sources. The report illustrates the pumping of water using wind energy with no emissions compared to fossil fuels. A windmill consists of a wind turbine coupled to a water pump to supply water from a reservoir to an area, which can be used by people in a community. The report shows the design and simulation of the different systems of a windmill. The project seeks to solve some of the problems faced in communities like lack of easy access to water, which has greatly affected many individuals and the economy at large, as people have to move long distances to access water. The existing technology of boreholes are difficult to use since they require pumping water by the use of hands and yet wind resources exist in some parts of the country which could pump water. The project study area was Karamoja with average wind speeds of about 4m/s and a static water level of 27m below the ground. The systems of the windmill were designed and the results shows that the wind speed produces 109.77W and a torque of 93Nm, which is sufficient to run a pump at a pressure of 19Mpa at a mass flow rate of 170Kg/s. The results show that a prototype can be developed in the next stages and tested to compare with the results from the simulation. If implemented it will be a good model to replace the hand pumping systems in existence. (1.987Mb)
