PROJECT REPAIR AND FABRICATION OF A REFRIGERATOR SYSTEM

INTRODUCTION  REFRIGERATION Refrigeration is a branch of science that deals with the process of removing heat from a substance or space in order to make it cooler. Refrigerator is defined as a device that is used in cooling the internal temperature below the room temperature (that is between 250C to 300C). Generally, however, for a space or substance to be cooler, it must loss that heat to another.  Also, for a space or substance to get hotter, it must absorb heat from another, which must b...

REPAIR AND REHABILITATION OF A FAULTY AIR CONDITIONER IN THE MECHANICAL ENGINEERING DEPARTMENT AT THE INSTITUTE OF MANAGEMENT AND TECHNOLOGY (I.M.T.), ENUGU

ABSTRACTIn the mechanical engineering department of institute of management and technology there are many machines but it is not all that is functioning well.This may airless as a   result of lack of maintenance which is a prove in the breakdown of the air conditioner.The quality and effectiveness of materials were mated very well as referred to machine maintenance.The cost of maintenance was minimized jet reaching a highly victorious rehabilitation.In the course of rehabilitation and repair...

FABRICATION OF A METALLIC BOOKSHELF

ABSTRACT  Knowledge could only be obtained successively by the use of books for research. This can be achieved only by preserving books already purchased. As a result we fabricate a metallic shelf made up of metallic sheet; precisely mild steel sheets. The mild steel used for the fabrication of the shelf is 1.5mm (16gauge) mild steel.  The shelf is made up of 3 partitions. In fabricating the metallic shelf several process where involved. We plundered on the material to be used that can hold...

DESIGN AND IMPLEMENTATION OF COMPUTERIZED STOCK STOCK MARKETING REPORT REPORT (A CASE STUDY OF NIGERIA STOCK EXCHANHE COMMISSION)

ABSTRACT Most Stock  Marketing Report, production, and manufacturing firms have the basic problem of information flow between the various departments within the organization. This research is intended to highlight the role of a computerized Stock  Marketing Report information system in NSEC Compare to the manual system of Stock  Marketing Report. To identify the various problems involve in the existing Stock  Marketing Report information system of NSEC is the purpose of this research and...

DESIGN AND IMPLEMENTATION OF COMPUTERIZED BUDGET ANALYSIS SYSTEM (CASE STUDY OF ENUGU STATE MINISTRY OF FINANCE)

ABSTRACT A Budget being the planning of how to spend revenues and incoming capitals so this makes is necessary to make sure that it is done with extra care. Budgets and the methods of preparing a good one has been a problem to most organization both private and government, the implementation of a faulty budget has brought man companies to a close door point were all operations are stopped.  Therefore budget design needs to be accurate and able to give account for every dime spent and on what...

DESIGN AND IMPLEMENTATION OF A COMPUTERIZED FINANCIAL ACCOUNTING SYSTEM FOR A HOTEL INDUSTRY (A CASE STUDY OF MODOTEL HOTEL, OKPARA AVENUE ENUGU)

ABSTRACT The importance of financial accounting is gradually being recognized as germane to prudent management of any business firm.  This has necessitated the need for the computerization of structured operations of the financial managers structured operations are known with certainly for instance, the computation and decisions based on financial ratios. This project therefore is a case study of Modotel Hotel.  It describes the computerization of the financial accounting of the hotel as pa...

CONSTRUCTION OF EQUIPMENT FOR DEODORIZING KEROSENE

ABSTRACT The motive of this project is to construct  equipment for deodorizing kerosene, hence the smell of kerosene is totally eradicated. The equipment was constructed with flat sheet plates of a desired standard, the dimension and the truncated parts were coupled and welded in order to fasten the parts together.  The material was selected to avoid the effect of rust due to the contact of the separating items or material with the walls of metal sheet. The effect of this equipment will be ...

CONSTRUCTION OF ORSAT GAS ANALYZER

ABSTRACT The Orsat Gas Analyzer was constructed at the project development institute (PRODA), Enugu.  The operation involved the laboratory glass blowing which entails the heating of a glass tube. The heating •continues until the glass tube reaches its plastic state. The shape of the tube is changed or the required shape blown by pulling, bending by hand, cutting with a knife and also blown with mouth or denting the shape by the application of a suitable tool.  The selection of the materi...

CONSTRUCTION OF A SIMPLE PAINT MIXER

ABSTRACT A paint mixer is defined as a pattern constructed for the production (mixing) of paint manually.  The method of fabrication of the paint mixer involved a preliminary computation of the dimensions of the standard mixer in relation to the dimension of the reacting vessel in which they will be used in marking out, cutting out to sizes, rolling, folding, welding, body-filling and painting.  The first step taken in the fabrication of this project work was the selection of material suit...

PRODUCTION OF PLANT MIRROR USING LOCAL RAW MATERIAL

ABSTRACT This project “production of plane mirror using local raw material” is meant to study the possibility of producing plane mirror using sand rich in silica as its major local raw material. Plane mirror is produced by casting one side of a sheet glass.  Presently in Nigeria, sheet glass is not used easily produce and as such, the local raw material used in the in the production of plane mirror in this product backing paint.  The facilities for the production include spraying gun a...

CONSTRUCTION OF STEEL CUPBOARD

ABSTRACT A workshop cupboard is a facility designed from mild steel for the storage of various materials, like book material and non-book materials e.g. workshop tools, labouratory wares and reagents, etc; after operations in a chemical labouratory, mechanical workshop, or else where. The construction of a workshop cupboard requires the consideration of lots of characteristics of the materials, which are used for the construction, such as physical and mechanical; chemical properties, service ...

ANALYSIS OF CRUDE PALM OIL

ABSTRACT This project was carried out to ascertain whether the local palm oil met the required standard.  The analytical test carried out include the free fatty acid test the acid value, iodine value moisture, content, saponfication value, peroxide value, specific gravity, colour and viscosity. The specific gravity of the oil sample was determined by comparing its weight when filled with the sample and that of water, while its moisture content was analyzed by oven drying the sample for a p...

THE CURRENT STATUS AND FUTURE CHALLENGES OF ELECTRICITY MARKET IN NIGERIA IN THE FACE OF DEREGULATION

ABSTRACT Electricity is fundamental and inevitable to our daily living as it lighting our environment, powers our homes, schools, hospitals, offices, businesses, and aid industrialization, It is a known phenomena that the economic growth of a nation rides on the wheel of electricity. While the telecommunication market in Nigeria has recorded advancement and stability, electricity market in Nigeria is facing mix challenges ranging from slow growth in generation capacity (generation capacity pe...

DESULPHURISATION KEROSENE

ABSTRACT This report aimed at determining the presence and removal of mercaptan sulphur in kerosene using colour indicator method.  It is known that impurities such as free sulphur, sulphur dioxide, marketers, finding materials etc. are found in petroleum products. Consequently, absorbents like molecular sieve, calcium oxide and even activated carbon could be used to trap these impurities, thereby making the  product impurity free. The afficac of  the absorption  using  calcium (Cao) �...

DESIGN THE ABSORBER (SCRUBBER) IN THE PROCESS PLANT FOR THE PRODUCTION OF 100,000 METRIC TONNES/ YEAR OF ETHANOL FROM DIRECT HYDRATION OF ETHYLENE

ABSTRACT The general approach to any design of a process plant involve an advanced network of chemical engineering process. Absorber is a process plant or equipment that are used in the purification of gas or separation of unwanted gas from the mixture when it comes in contact with the liquid. In this models mass transfer reaction and equilibrium process as they prevail in conventional tray absorbers and in cascade of trickle bed reactors are incorporated. Owring to the mass transfer characte...
