Abstract This project work centered on construction of 12V/10A solar charge controller that is needed in photovoltaic system to safely charge regulate and discharge of sealed lead acid battery through DC load. Solar charge controller is devices that regulate solar photovoltaic power and prevent overcharging, over discharging or overflow of current that reduces the lifespan, durability and performance of the battery. The12v/10A solar charge controller was constructed using variable resistor, ...
The aim of this project is to shows the possibility of wireless power transfer through the design of a wireless charging pad. In this project write-up, the methodology and principle of operation is wireless power transfer through inductive couple, a feasible design is modelled accordingly. The inductive couple technique is used because it is the easiest method of wireless power transfer with high efficiency and large amount of energy transfer. This report showed the versatility in range of a...
Abstract This project work was embarked on the construction and determination of the efficiency of 12 volts DC fan using two N3055 transistor, 1kΩ variable resistors, resistors, breadboard, veroboard, 12 volts DC battery and connectors at Science Laboratory Technological Department, Federal Polytechnic Offa, Nigeria. This is always required to minimize, control or totally eliminate the power fluctuations received at the load end or consumer end that usually lead to the reduction of DC fan li...
ABSTRACT In our present society, wireless communication has become most prevalent and mobile units (hand held devices /GSM/ Computers) are one of the most common equipments for conveying messages wirelessly. Owing to the fact that most youths in our society today on the average make use of at least one wireless device that communicate with other wireless devices via the internet, has made engineers start to think about ways to improve the quality of service (QOS), throughput, spectral effic...
ABSTRACT Biomass is organic materials that are made from plants and animals. Biomass stored alot of energy from the sun. Biomass is renewable sources of energy which can grow more such as trees and crops, and waste always exist. Example of this biomass may include wood, forage crops, manure and some garbage and alcohol fuels. The usable forms of energy suc...
ABSTRACTThe design of a 1000 tonnes per annum Shea butter plant was carried out using data obtained from literature. Assumptions were made, where experimental data were not available. The block diagram, process flow sheet, material and energy balance on the process was carried out and presented on this work. A total of six units were used in the design, comprising of the dryer, de-sheller, roaster, expeller, filter and refiner (reactor). The plant is expected to operate for eight hours per da...
ABSTRACTA study on the effects of post- harvest variables on the yield and quality of Shea butter wascarried out. The Shea nuts acquired from villages were divided into five batches with avillage/uncontrolled sample. Each batch was boiled at different time ranges (0, 15, 30, 45 and60) minutes. Each batch was dried through an oven drying method. Also, each sample wasdivided into two equal parts and was cooked for 30°C (room temperature) and ...
Crude oil viscosity is an important parameter which is considered in both porous media and in pipeline channels. Estimating oil viscosity at various operating conditions of pressure and temperature is of great value to petroleum engineers. In petroleum and reservoir engineering, we are often faced with the analysis of processes which involve petroleum fluid properties, but in many cases no experimental data is available. At such cases, empirical correlations are used to estimate the oil visco...
ABSTRACT Composites have been developed with great success by the use of reinforcement. Monolithic materials cannot possess all the properties to be obtained hence, the need to employ the use of composite materials. Aluminum is generally utilized as a basic material particularly in the aerospace industry in view of its light weight property Be that as it may; the low quality and low melting point were continuously an issue.However due to these limitations, intense exploration on the use of me...
ABSTRACT Security concern have existed since time immemorial. But the challenges has never been as readily manifested as they are presently. This is rather disconcerting. Moreso, because some of the security challenges and problems we encounter daily in the contemporary society are almost entirely unpredictable. Indeed, rapid growth and use of mechanical arts, applied science, and revolutionary dynamics of society apparently blend well with the desperate nature of the criminally minded to ...
The aim of the project is to develop a numerical tool used to predict vessel motions of a turret moored FPSO, then perform a comparative analysis between the 6 degree of motions measured on the FPSOs during the 7 months period and the predictions from this numerical model. The first step was to carry out statistical and extreme value analysis of the metocean data obtained from hindcast and measured data, this gave an insight to the characteristics of the measured data and how it closely relat...
The fast growing and developing population of the world is so busy that instant food noodles are gaining ground for both humans and domestic animals. Incidentally, the machines involved in the production of these food noddle extruders are imported which results in the depletion of our foreign exchange reserve. Consequently, there is a growing need to design and produce these machines locally. This project has achieved the design, fabrication and testing of noddle extruder. The fabrication is ...
ABSTRACT-Power system planning is a vast and important issue for operation and expansion of power delivery. One of the basic objectives of planning is to determine the right schedule for investment in new devices which ensures secure and economic power delivery for predicted customer demand. System planning also addresses the question of reliable and stable operation; hence reliability and stability analysis are also included in adequate power system planning studies. This work explores the a...
ABSTRACT This research work was carried out to evaluate the different methods of corrosion prevention, control and monitoring. In the course of the research many scholarly articles on the subject matter were reviewed from which the researcher got lot information concerning the topic at hand. Thus making the research work a reliable source of information as far as facts about corrosion is concerned.
