The equipment operates on the principle of evaporative cooling and increasing the relative humidity of the interior of the equipment. The door and the back wall were of particle board of 12mm thickness while the two sides are made of jute bag through which water flows on a trough at the top flows with the influence of gravity. The facility designed w...

EFFECTS OF SOIL PROPERTIES ON ERODIBILITY AND INFILTRATION: A CASE STUDY OF UNAAB HOSTEL

ABSTRACTErodibility of UNAAB soil series for nine plots behind the female hostel ( i.e. plot A – I) using regression equation were determined by evaluating first organic matter content, using the Walky Blanks method, the particle size analysis, permeability test, bulk density and chemical properties of the soil such as Sodium, Cation Exchange Capacity, acidity, Potassium, Magnessium and calcium.The organic matter content of the soil(Ibadan series-sandy loam) was found to be;plot1 depth...

MODIFICATION OF A COCONUT OIL EXTRACTOR

ABSTRACTA prototype of hydraulically operated coconut oil extractor was designed and fabricated. The machine can be used for other oil-bearing seeds such as groundnut and palm kernel. The machine is made up of a plunger, ram disc, expression chamber, and electric heater. The extractor can process 10kg coconut per hour.An efficiency of 15% was obtained from the coconut cake of 2.9kg (wet basis). While for the dry basis 40% of oil was obtained from coconut cake of 2.5kg.TABLE OF CONTENTTITLE PA...

THE INFLUENCE OF RAINFALL DURATION ON SPLASH PRODUCED FROM A LOAMY SAND SOIL

ABSTRACTAt the event of soil erosion, rain splash erosion supplies materials for subsequent transportation and entrainment. The influence of rainfall duration on splash produced from a loamy sand soil in Camp area of Abeokuta, Ogun State was studied in the laboratory using a laboratory rainfall simulator. The study area is always subject to serious erosion. The objectives of the study are to analyze the characteristics of splash erosion on the soil due to different rainfall duration at differ...

THERMAL CONVERSION OF PALM KERNEL SHELL AND MESOCARP FRUIT FIBRE INTO FUEL

ABSTRACTPalm Oil processing yield a considerable quantity of palm kernel shell (PKS) and mesocarp fruit fiber (MFF). This has been predominantly used as fuel through direct combustion which is inefficient and polluting. Better grade fuel could be derived through torrefaction. The objectives of the work therefore was to determine the optimum parameters for the conversion of palm kernel shell (PKS) and mesocarp fruit fiber (MFF) to high grade fuel via torrefaction. Samples of PKS and MFF were t...

DETERMINATION OF CROP COEFFICIENT OF A VARIETY OF MAIZE(ABONTEM MAIZE)

ABSTRACT In a study at KNUST weather station, the crop co-efficient values at initial, development, mid-season, and late season stages of ABONTEM MAIZE (hybrid variety) were determined as 0.42, 0.98, 1.05, and 0.32, respectively. These locally determined values of ABONTEM hybrid maize compared favourably with those recommended by FAO. The corresponding FAO values are 0.4, 0.80, 1.15, and 0.70. The FAO values are average values...

DESIGN OF AN ORANGE COLLECTOR

Equipment development in Ghana to harvest oranges have over the years focused on simple units such as Garden tool, basket style picker etc. and common methods of harvesting oranges in Ghana are the use of manual branch shaking, manual pull with the hook stick. The effects leads to:Infestation of a bacteria called Alicyclobacillus when the fruits fall on the ground.The bacteria lives on the fruit which contaminates it.Bruises through impact on the hard surface.The main aim of this study is to ...

CONSTRUCTION OF A MOTORIZED CASSAVA PEELING MACHINE

ABSTRACT The motorized cassava peeling machine is a type of cassava peeling method that is adopted to reduce drudgery. In cassava peeling operations. This method, unlike the manual peeling method which consumes a lot of human power with subsequent low output produces or peels a large amount of cassava tubers within a small specific of time and small amount of flesh loss and finally low demand of power. this paper presents the design and constructing of a motorized cassava peeling machine...

DETERMINATION OF THE CONSUMPTIVE USE (EVAPOTRANSPIRATION) OF GROUNDNUT (A CASE STUDY OF A GROUNDNUT FARM LAND IN AWHA IMEZI, EZEAGU LOCAL GOVERNMENT AREA OF ENUGU STATE)

ABSTRACT   The consumptive use of water assures all year round production of groundnut prone to the vagaries of weather and climate. This brought about the need to supply moisture that is naturally available through rainfall. The successful design of any irrigation system requires the knowledge of the consumptive use of water by the crop under consideration. This need led to the investigation of the water use rate of groundnut in a typical area found in Awha-Imezi of Ezeagu in Enugu...

EVALUATION OF THE EFFECTS OF ANTHROPOENIC ACTIVITIES AND DOMESTIC WASTE ON SURFACE WATER QUALITY (A CASE STUDY OF EKULU RIVER, ENUGU).

ABSTRACTThe microbiological and organic pollutants characteristics of umuosoko stream in ikwuano local government area, Enugu state, Nigeria were carried out. Twenty water samples were collected from four different parts of the river.  The pour plate technique was employed for the isolation of micro-organisms. Colonial morphology, Gram staining and biochemical tests were used for identification and characterization. The statistical analyses used were analysis of variance and standard dev...

EVALUATION OF THE EFFECTS OF FLOODING ON THREE VARIETIES OF RICE (A CASE STUDY OF ABAKALIKI, EBONYI STATE)

ABSTRACTFlooding has been described as one of the most important environmental factors determining the distribution of salt marsh plants. We studied the impact of five water levels on the germination and establishment of the invasive cord-grass spartina deniflora. Plant house experiment was carried out to determine the effects of time and depth of flooding on the survival and growth of rice. Data showed that time and depth of flooding had significant effects on the survival and growth of rice...

Design and Performance Evaluation of a Waste water Treatment Plant.

The study aimed at the design, construction and performance evaluation of a model domestic wastewater treatment plant was carried out. The treatment unit was a Waste Stabilization Pond (WSP) comprised of one facultative pond, three maturation ponds, and a contact filtration unit, all in series. The effluent of the WSP, after filtration through clay media, had the BOD reduced to 15.4mg/l, from 356mg/L indicating a 95.67% removal level. A Faecal Coliform (FC) count of the influent sample gave 1...
