It is divided into chapter, which discussed extensively the practical refrigeration cycle with full attention given to design factors, working principle and choice of material. The method used in construction, assembly and arriving at knowing the safety requirements were not left out. TABLE OF CONTENT Title page Letter of Transmitta...
ABSTRACT This write up focuses attention on a detailed report and account on the process of construction and formulation of plan for the actual and physical realization of the construction of the project work captioned fabrication and construction of a mobile cooling system. The report is therefore divided into chapters and each chapter discussed extensively such that an illiterate refrigerator mechanic who read and comprehends the report can easily carryout the construction of refrigerator...
Company background and overview Anbessa City Bus Service Enterprise is the largest City Public Transportation Company in Ethiopia established immediately after the Italian invasion in 1943 by collecting old vehicles and garage equipment from the invader. At the time its name was Public Transport and guided by Italians and other foreigners. In 1952, it was organized in to a share company by getting legal entity from the government. At that particular year the enterprise had only 10 buses t...
INTRODUCTION Nigeria is an agricultural nation. Melon (Citrullus Vulgaris) is widely cultivated in Nigeria, among other seedlings during the planting season yearly. Several tones of the melon seeds are gathered each harvesting period but only very low percentage of the total harvest are dried by atmospheric draught and bagged for storage. High percentage waste is encored due to lack of good processing and storage facilities.Melon when properly processed yields a lot of by-products, which co...
ABSTRACT This Machine is design and fabricate as a prerequisite for the award of a Higher National Diploma. We sketch different designs which after consideration of many factors like the machine efficiency, the cost of materials e.t.c before we finally embark on this machine.The machine major component are the shaft, the inner barrel, the outer barrel, the conveyor, the tray etc.The machine is build with very strong and well selected materials which enhances the performance of the machine. ...
ABSTRACT The project work titled Design and construction of a metal detector. When fully design and implemented would be able to detect any metallic material that is passing or coming close. This function would serve as a security check for dangerous metallic material as an alarm. Going by the sophisticated means of armed rubbers adopt these days in the breaking into bank supermarkets offices and highly secured area. No security system will be optimised or complete without the installation of...
ABSTRACT This research is centered on the design and fabrication of copula furnace and atomizer for the production aluminium powder metal with the available material.0.4kg of refined coke was chosen as the basis for material and energy balance calculations and the design calculations performed from whose values are used to produce the design drawings.Mild steel was used for the internal linings of the furnace casing while other materials were selected based on functionality, durability, cost ...
ABSTRACTPackaging of food which is viable means of business opportunity has been exploited by individuals and corporate bodies for a very long time because the importance of packaging food products are very enormous ranging from protection of the product to preventing the food from spoiling. There is no way one can successfully go into business of chips production without exploiting a proper means of packaging the product. Over the years, different types of packaging machines have been deve...
ABSTRACTAn escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of usage are; shopping malls, airports, transit systems, convention centers, hotels, and public buil...
ABSTRACTBrazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel as based filter material in air or atmosphere the braze joint will porous and braze strength is not achievable. To avoid the presence of oxygen while brazing, either inert gas furnace or vacuum furnace can be used. Vacuum furnace is superior to inert gas controlled by furnace ...
ABSTRACTThe designed Air Driven Engine is an economic friendly engine which operates with the aid of a compressed air. In principle, an Air Driven Engine uses the expansion of compressed air to drive the pistons of an engine. An Air Driven Engine is a pneumatic actuator that creates useful work by expanding compressed air. There is no mixing of fuel with air as there is no combustion.An Air Driven Engine makes use of Compressed Air Technology for its operation The Compressed Air Technology is...

INTRODUCTION The purpose of a control system is to produce a desired output. This output is usually specified by a command input, and is often a function of time. For simple applications in well structured situations, to control, and the controller must have the capability of reacting to disturbance, changes in its environment, and new input commands. The keys element that allows a control system to do this is feedback, which is the process by which a system’s output is used to influence ...
INTRODUCTION Communication means extending information form one person to another in a way in which it can be understood. Information and ideas in technical and scientific fields can very often be more easily communicated through sketching or instrument drawing and blueprint reading. Drawing involves describing the shape and size of an object. CHAPTER ONE Preambles Types of Engineering Drawings CHAPTER TWO 2.1STAGES IN THE DEVELOPMENT OF A NEW PRODUCT 2.2THE DRAWING OFFICE 2.3PRINT ...
ABSTRACT This project work-up deals on the design and construction of a single phase step down nations fermor, with raking IKVA, 240V/11OV, 80V 12U, 6V. It is a multi-circuit transformer that has one input as the primary and tappins to produce the output (secondary). It is considered as a single coil in series with the supply and a common coil to the head. It is experimentally done using flat metal shocks of cast steel to form the “E” and “I” shaped laminations and coils of various tu...
