Performance of a solar powered irrigation systems in the Northern Ghana was evaluated in this study. Solar powered water application systems (drip, spray tube and sprinkler irrigation systems) were evaluated using performance indicators. Coefficient of variation (CV), emission uniformity (EU), emitter flow variation (Qvar) and mean application rate (MAR) were evaluated for the drip irrigation system for different water levels in the tank. Uniformity Coefficient of (CU), Distribution Uniformit...
Groundwater resources have been heavily dependent on for domestic and agricultural purposes since the beginning of time. This study was therefore aimed to evaluate the significance of physical and environment factors on groundwater potential, delineate the groundwater potential zones and determine the water quality in the Wa Municipality of Ghana for irrigated agriculture. Nine (9) layers namely; Geology, lineament density, rainfall, drainage density, soil, landuse and landcover (LULC), topog...
Abstract Modern vertical axis wind turbine is a promising technology, appropriate for small scale applications in urban areas and isolates sites for different uses. Including pumping water, producing electrical power, passive starting others turbines and purposes. The Savonius wind turbine is a robust and reliable mechanical device, easy to build, produces less noise. The formation and growths of cracks in this system reduces its stiffness and yield strength, which lead to a poor performance ...
Abstract: This study was undertaken in Kitui South in Kitui County in the south eastern parts of Kenya. The main objective of the study was to develop a spatial model that can be used for selection of suitable sites for sand dam in Kitui South. Data analysis was done using three approaches. The first approach involved the use of the Remote Sensing (RS) technique where data was preprocessed and analyzed using Erdas Imagine software and Geographical Information Systems (GIS) for spatial modell...
Abstract: Biogas is an alternative source of energy that is produced by methanogenic bacteria through the bio-degradation of organic material under anaerobic fermentation of organic matter conditions. The aim of this study was to determine the optimal mix ratio for biogas production from anaerobic digestion of mango fruit peel and cow dung. The experiment was batch operated and daily gas yield from the mixture was monitored for 30 days. The parameters measured were total solids (TS), volatil...
Abstract: Ethanol produced by microbial fermentation of biomass is used primarily as a substitutive for gasoline. It is produced by using an eco-friendly method to replace fossil fuel. Therefore, this study was focused on co-fermentation of orange and papaya fruit peels waste for bioethanol production with the objective of evaluating its potential for ethanol production with different concentrations (100 g orange peel, 75 g orange peel +25 g papaya peel, 50 g orange peel +50 g papaya peel, 2...
Abstract: Biogas is eco-friendly alternative renewable energy source produced through anaerobic digestion of organic compounds. In this study, biogas production was evaluated from sawdust (SD)and cow dung (CD) co-digestion in five mix ratios under mesophilic conditions (35ºC) using batch digesters in the micro biology Laboratory of Haramaya University to evaluate biogas production potential of sawdust through anaerobic digestion alone or in combination with cow dung .In 100%SD , 100% CD, 50...
Abstract: The unsustainability of conventional energy resources and their associated environmental pollutions made renewable energy the prime need of present time. Therefore, the research was conducted to investigate the production of biogas from Striga hermonthica co-digested with cow manure through anaerobic digestion with five treatment mix ratios were evaluated under mesophilic conditions (38ºC) using batch digesters in the Botanical laboratory of Haramaya University for 30 days of ferm...
Abstract: Production of biogas through anaerobic digestion of organic waste materials provides an alternative eco-friendly renewable energy source. With the aim of biogas production from codigestion of Cow dung and Ricinus communis leaves, a series of experiments were carried out under mesophilic conditions at 38 ºC using batch fermentation for 30 days. Anaerobic fermentation were carried out by mixing the substrates in five different proportions to obtain suitable mix ratio for maximum bio...
Abstract: Bio-ethanol is a clear liquid alcohol that is made by the fermentation of different biological materials. it is being considered as a potential liquid fuel due to the limited amount of natural resources. This study was undertaken with the objective of producing bio-ethanol from leaves of Desmodium triflorum by fermenting for 16 days. The leaves were first pre-treated with dilute sulfuric acid to ease the hydrolysis of lignocelulosic material and incubated in different substrate con...
Abstract: Alternative energy sources have recently become more and more attractive due to the increasing demand for energy, global warming, depletion of fossil fuels and high prices of petroleum-based fuels. One of the alternative sources of energy is Biogas. In this study, Guizotia scabra sub-species scabra was evaluated for its potential of biogas production codigested with Cow dung (CD ) in five mix ratios under mesophilic condition (38ºC) using batch digester in Botany laboratory of Har...
Abstract: Biogas is eco-friendly alternative renewable energy source produced through anaerobic digestion of organic compounds. In this study, biogas production was evaluated from Prosopis juliflora leaves(PJ) and cow manure (CM) co-digestion in five mix ratios under mesophilic conditions (38ºC) using batch digesters in the Botany Laboratory of Haramaya University to evaluate biogas production potential of Prosopis juliflora leaves through anaerobic digestion alone or in combination with co...
Abstract: Bio- ethanol is suggested as a sustainable fuel which can be produced from renewable resources and reduce the level of greenhouse gases. Therefore, this study was focused on producing bio ethanol fuel from teff (Eragrostis tef) straws in batch fermentation using yeast (Saccharomyces cerevisiae). Fifty grams of acid pretreated and untreated teff straw were incubated with10ml of 1% of yeast under three different temperature (20℃, 30℃ and 40℃) treatments and allowed to ferment o...
Abstract: Biogas is a clean and renewable form of energy and well substitute for conventional sources of energy especially in the rural sector. In response to the need for addressing the adverse impacts of the increasing trend in biomass energy consumption in Ethiopia, the last three recent decades development of more efficient cooking stove technologies and alternative sources of household energy had been realized. The aim of this study was to determine the optimal mix ratio for biogas prod...
