ABSTRACT A 1.25KVA (2000W) inverter generator was designed, constructed and certified Ok. In this project, the design of the inverter generator is aimed at satisfying the need of converting, a D.C source of supply (12v battery) to an A.C voltage of 220v. The inverter range of output is between 200-220v. Since the inverter was designed to step-up voltage, the power transformer is being used as step-down transformer for charging and as step-up transformer for inverting. The control circuit e...
ABSTRACT The main objective of this project was to ensure a proper security to car being parked in garage against theft or an intruder. The circuit uses three NE555 timers; one of the NE555 was wired as a monostable oscillator and remaining two were wired as tone generator and amplified to obtain a maximum audible sound. However, pin 2 of the first NE555 was used as sensor part .When pin 2 has contact with human body or hand it will activate the IC1 which will also bias transistor and this t...
ABSTRACT Palm 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...
ABSTRACT At 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 diff...
ABSTRACT A 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 CONTENT TI...
ABSTRACT Erodibility 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 d...
ABSTRACT A 1.05 cubic metre capacity storage facility which is to increase the shelf life of stored vegetables as designed fabricated and tested. 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...
ABSTRACT When it comes to construction projects, landscaping work, and gardening, you need the right kind of equipment to finish tasks speedily and easily.

There are a lot of equipments that can be used these days for projects that involve heavy work. It would be an advantage to utilize motorized equipment in order for you to do tasks efficiently. With these tools, it ...
ABSTRACT Food is inevitable in ones life and fish is a main source of vitamins and protein in ones life. Fish pond is a place for growing fish for commercial or private needs or gestetic purpose. The design of fish pond is very important because of its aqueous retaining nature which if there is leakage will not only cause loss of water but also loss of lives of fish and plants in it. A adequacy and accuracy is relevant in the design of fish pond. The engineer is bordered with the functions o...
ABSTRACT The production of high quality foam was carried. The actualization of the production of polyurethane (fibre) foam was made possible by using the components / chemical raw materials such as polyol (polyurethes resin). TDI (toluene di-Iso-cyanate, methylane chloride (MC)-(CH2CL). Silicon oil, stannous octoate, calcum carbonate and water. As a result of chemistry of polyurethane foams, properties of foams and fibre materials (physical, chemical, thermal and mechanical properties...
ABSTRACT This project “The Production of Ceiling Board from Local Raw Materials†was carried out basically using raw materials which was sourced locally. These raw materials are found to be very much in abundance. Some are materials sourced from the ground and others are from agricultural wastes. Three different types of ceiling boards were produced, their difference being in the type of fibre that was used. The fibres used for this different type includes; cellulose fibre obtaine...
ABSTRACT This project “Extraction of oil from a local seed (groundnut oil) and Characterization†was carried out using ten cups of groundnut seeds that was purchased from a local market in Enugu metropolis. The oil these seeds were in Enugu using solvent extraction method. Two different solvents were used in the extraction namely: Ethane and order to compare their yield, physical and chemical properties. The extraction was carried out using 32og of size-reduced groundnut with 1...
ABSTRACT This research was carried out with the sole aim of monitoring interface in the transportation of petroleum pipeline products and the analysis of this product from Enugu depot. In the research it was observed that product contaminates each other if interface was not properly monitored and cut at the appropriate time. The three major products that were considered in this research were premium motor spirit (PMS) automotive gas premium (AGO) and dual purpose kerosene (DPK). The tes...
ABSTRACT Adhesive is a substance that holds materials together by surface attachment, while wood adhesive is a substance that is used to hold plywood for furniture works. This substance is essential and has universal applications. Thus the aim of this research work is to produce it using cassava starch as a base binder. Starch is also used in industries to produce ethanol and glucose for textile industries, laundry and paper adhesive industries. It is of great importance to paper, wood and ...
