ABSTRACT As the zeal for change over on public power supply and stand- by generator increases; Engineers have researched deeply into the different ways and methods of achieving power changeover both manual and automatic types. It may no be considered as serious issue in some places where supply is up to 90% constant or where intermittent outage cause no great damage. However, places like the business confers, industrials and cold rooms need almost 100% power supply, and also hospitals and use...
ABSTRACT This project write up of a step – down transformer from 220v to 24v:12v, this is to expose what a transformer is all about and its important and uses. The aim of the project, step-down transformer is to show Electrical and Electronics Engineering, could step-down the voltage from 220v to 24:12v, and fro this project write up. They are divided into chapter by chapter. 0.1Chapter one is the introduction to a step – down transformer from 220v to 24:12v. 1.1Back ground...
ABSTRACT This project work is on the construction of an F.M transmitter this system consists of four discrete modules namely the audio frequency (AF) amplifier (class A) the modulator the master oscillator and the radio frequency (RF) amplifier (ClassC) these formed the conventional events for building FM transmitter here the signal (from the microphone) is fed into the (AF) for amplification then to the modulator which combines the modulating signal with the carrier wave transports the mod...
ABSTRACT The practical importance of a battery charger in today world cannot be over emphasized. This is so as those batteries accumulators are immensely needed by out auto mobile and in science laboratories. This thesis describes the methodical approach to the design and construction of any battery charger. However the procedure fro developed cover the construction of battery charger for battery sizes ranging from 6 voltage to 24volatge (heavy duty) batteries. The prototype of a batter...
ABSTRACT This project, 12v battery charge consist of few chapters, deal extensively with the design and construction of a batter charge which is capable of charging a 12v battery. The introductory chapter goes a long why in defining the battery charger and explanations of the mode of operations will be death with as we proceed. TABLE OF CONTENT Construction of a 12v Battery Charger Approval Dedication Acknowledgement Abstract CHAPTER ONE 1.1 Introduction CHAPTER TWO ...
ABSTRACT The battery which has always serve as a sources of electrical current has in the past been invalid and inmost cases seen as monument after implicating as battery wound have to be brought over and over again the implicating has been that of lot of money is been spent for this purpose we give appraise for the advancement of technology which today had led to the production of battery which could be made functional after it energy may be used up this has been made possible by rechargin...

The combination of contactors overload relay and other component to achieved the desired goal is diagrammatically and descriptively treated of practical knowledge TABLE OF CONTENTS Title page Approval page Dedication Acknowledgement Abstract Table of contents CHAPTER ONE 1.0Introduction 1.1Background 1.2Aim and obje...
ABSTRACT Audio loudspeaker (output transducer) is on of the most essential and powerful device used in telecommunication system. This is device capable of converting electrical signal into sound and vice versa. It is made up of few time of non-magnetic wire wound on a light cylindrical former that is mounted so that it can move freely insides the magnetic field of a strong permanent magnet. The speaker cone it attached to the voice coil and attached with a flexible mounting to outer ting of...
ABSTRACT This project is concerned with the fabrication of as a single face pressurized kerosene cooker. The report shows the possible way in which the above mentioned can be designed, fabricated and maintained. Its also shows the strength and properties of the materials it is made of. Defects of the equipment can come through inability to maintain and inability to use well. It can be due to irregular cleaning of pressurized parts, exposure to rain, moisture and sunlight as well as i...
ABSTRACT This work on the construction and fabrication of a mobile deep freezer revolves around the concept of refrigeration. The concept of refrigeration revolves around the reverse Carnot cycle. This is a cycle involving isentropic expansion (at the throttling valve), isothermal expansion (at the evaporator), isentropic compression (at the compressor) and isothermal compressor ( at the condenser) Compression raises the temperatures of the refrigerant above that of its natural surrounding...
ABSTRACT Mechanical Engineering Department of the named Institute has many non – operational malhiues. Sequel to the fact, maintenance was poorly excuted which resulted to the breakdown deep freezer. Quality and effectiveness of machine maintenance were well observed. Also, a minimized maintenance and a highly successful repair was adopted. In other words during the repair and rehabilitation of the facility Deep Freezer, appropriate tools, cost and quality of materials were well...
ABSTRACT Books are used recoding of what is happening or event that has already taken place which can be storing information it is useful and for the information that such books contained not to cost it support to be properly kept and these can be done when those books are kept in a cool dry place and a place free from rodents and insects attacked Therefore, our contribution to proper storage of books is the deigns and construction of a metallic bookshelf that will be economically cheap an...
ABSTRACT This work is an attempt evolve a quicker and easier method of achieving Transportation. This will no doubt save considering human labour and time wasted involved in traditional manual method of transportation. To achieve this, preliminary experiment was first carried out to determine the optimum speed of the motor vehicle. Various design alternative s for achieving the design solution were sythesized and a choice of an economic method which would satisfy the objective was made. Base...
ABSTRACT This project was Carrie lent using sub-bituminous coal and crude palm oil. The degree of bleaching of the palm oil was monitored with a spectorphoto meter. The coal was collected in a lump from the mine. It air-chiecl to removed the moisture content and thereafter, size reduced to a small particle size foe effective activation. The activation process was carried out in a fume cup board and phosphoric acid was used as an activated agent. In the treatment of palm oil, sodiu...
ABSTRACT Water Purification Unit or filtration unit is designed in way that it will give a nice result. Like in our filtration, we have sand and carbon filter that were responded to separate the suspended solid particles, odour and taste of the water, which will give a very nice filtered water at the end of the filtration. This unit has no chemical engineering operation, but a physical separation process that will separate the dead micro organisms and the task, colour odor of the water. ...
