ABSTRACT SWAT was applied a large watershed (3,765km2) in south-eastern Nigeria, to predict streamflow and sediment discharge from the Ebonyi River Watershed using globally available data downloaded from the internet. Digital elevation, land-use and soil maps of the study area from global databases and historical weather data measured locally were used. SWAT model was setup to use the MapWindow GIS interface. The model predicted  an  average  daily  streamflow  and  sediment ...

ABSTRACT Biomass is naturally abundant in rural communities but is generally considered to be a waste in most developing countries of the world where it is used inefficiently in its traditional form. The effective utilization of these materials offers many advantages among which is a renewable and sustainable energy feedstock for the production of solid fuel – briquettes - for heating applications. Attempts have been made in developing machines for ...

ABSTRACT Baking and roasting are important cooking operations domestically and commercially carried out in bakeries, eateries and homes. It involves cooking with hot air as a result of heat and mass transfer processes. Baking and roasting of food items could be done using an oven. Therefore, this work is aimed at harnessing agricultural waste materials as heat sources in oven cooking and baking operations. The design, construction and performance evaluation ...

ABSTRACT Technology of milling and grinding machine is one of the simplest methods of  processing  agricultural  raw  materials  alternative  to  the   traditional methods of grain/tuber processing using stone, mortar and pestle. However, machines  constructed  using  metal plates  results  in  tearing  and wearing away of the materials of construction. The effect of this is the contamination of  the  processed   foodstuff.   This  is  known   to  have  negative   health implications when accumulated and ...

Abstract Lack of access to potable water by a significant percentage of the populace in developing countries  contributes  immensely  to  the  large  number  of  deaths  and  illnesses  recorded annually from water borne diseases. Point-of-use water treatment methods are usually recommended to curb water borne diseases in developing countries. The commonly used methods in households include; boiling, use of filters and chlorination. These methods have shortcomings such as high fuel and ...

Abstract Hydrological    models   are   useful   tools   for   prediction   and   understanding    of  hydrological phenomena which underpin watershed resources utilization. A watershed model simulates hydrological   processes   in  a  more  holistic   manner   across   the  entire  watershed   area.   Most watershed  models  are  fairly  complex;  interactions  among  watershed  hydrological  components are  essentially  nonlinear  and  take  place  on  a wide  range  of temporal  and  spatial  scales.  The Watershed   Resources   Management   (WRM) model  was  developed   in  Canada  ...

Abstract Most previous hydrological studies advanced mainly by collection of data from field. This research aimed at developing and testing of a hydrological cycle demonstration system using a rainfall simulator as a laboratory scale model. Locally available materials were used to construct the model. It has six major components: reservoir, plot (sandbox), water pump, simulator,  network  of  pipes  and  frame.  Some  rainfall  characteristics  like  intensity, distribution uniformity, drop size diameter, ...

ABSTRACT The modification of a single-rotor cassava grater was undertaken. The single- rotor grater was modified into a double-rotor self-action grater and its performances evaluated by determining its throughput capacity and efficiency. The  throughput  capacity  was  determined  by  grating  known  quantities  of cassava roots  in  three respective runs and  the  time  taken to grate  them measured from a stop watch. The efficiency of the machine was calculated from the quantity ...

ABSTRACT Intensive piggeries are predominating livestock production and there is rising concern of nutrient pollution from the use of floodplains and water bodies as convenient sinks for the disposal of untreated wastewater. Successful removal of nutrients in piggery wastewater by constructed wetlands has been reported in different climatic regions outside Nigeria and their optimal design, performance, effects of plants and climate change on performance and the prediction of these effects ...

ABSTRACT Biomass Briquetting can address waste problems, reduce air  pollution from direct open air burning and also reduce dependence on fossil fuels for heat generation. Dry leaves have been shown to have high calorific values; therefore the purpose of this study is to determine the effects of some binders on the physical and combustion properties of dried leaves briquettes. Dried leaves were mixed with binders such as clay, starch and ...

ABSTRACT A biofiltration wastewater treatment pond was developed and the performance evaluation undertaken at the Department of Agricultural and Bioresources Engineering, University of Nigeria, Nsukka, southeast, Nigeria.  The biofiltration wastewater treatment system is made of three compartments comprising a wastewater storage unit, wastewater treatment unit and treated wastewater compartment.   The compartments are of the same size with the following dimensions 0.61m x0.61m x 0.5m having a  volume of 0.1861m3. Wastewater ...

Abstract Waste collection in Enugu has been a major challenge requiring urgent attention. The aim of the work therefore was to study with GIS the management of the existing bin distribution and collection system in order to determine the optimal frequency for waste collection. The methods adopted include questionnaires, oral interviews and field observations to determine the state of waste collection. Waste collection points both legal and illegal dumpsites were ...

Abstract In this study the design, construction and testing of a hand operated water pump was undertaken. The major components of the pump were the pump frame made from angular bar mild steel, the pump chamber made of mild steel, the pump cylinder made of cast iron, the pump crankshaft made of hollow galvanized iron pipe, the connecting rod made of hollow galvanized iron pipe and the pump inlet and ...

ABSTRACT The present study designed, constructed and undertook the performance evaluation of a post harvest passive solar crop dryer for drying agricultural produce. The solar crop dryer consists of a solar collector with dimensions 110 x 61 x 10cm, a drying chamber measuring 102 x54cm, a movable heat storage unit with the dimensions 40 x 35 x 13cm and drying trays each having an area of 1806cm2. The performance evaluation ...

ABSTRACT A study was undertaken to developed a model that will be used to predict sugar and the by-products from sugar cane. The model developed from MATLAB was used to predict the sugar, bagasse, filter cake and molasses yield from sugar cane. The predicted values from the model were compared to yield data obtained from the production of sugar cane from the  Savannah Sugar  Company,  Numan,  Nigeria  for  90  days. ...

Abstract This study was on the impact of radio programmes in the development of rural areas. Three objectives were raised which included:  Find out the extent to which residents of Awgu listen to radio programmes on development, find out how often the residents of Awgu listen to radio programs, ascertain whether the residents of Agwu have experienced development through listening to the programs and ascertain the challenges preventing the development ...

Abstract The purpose of this study was to obtain a detailed comparison of engine performance and exhaust emissions from natural gas and gasoline fuelled spark ignition engines. Each fuel was tested at both wide-open throttle and two part-load operating conditions over a wide range of air—fuel ratios. The results show that the power output of the engine at a given throttle position was reduced by about 12 per cent when fuelled by natural ...
