Public Transportation: The Role Of Government And Private Enterprise

ABSTRACTTransportation is a requirement for every nation, regardless of its industrial capacity, population size or technological development. The Nigerian transport systems, right from inception, were poorly designed and are unable to scale up to meet greater demand, a design flaw which causes traffic congestion on roads, overstressed railways, faltering airfields, and mass-transport blind spots. Overall there appear to be market impediments which operate to limit the extent to which Nigeria...

DESIGN AND CONSTRUCTION OF A SINGLE PHASE AUTO-TRANSFORMER OF RATING IKVA, 240V/110, 80 12V, 6V

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 ...

WASTES AND SEWAGE AS A SOURCE OF ELECTRICITY GENERATION

ABSTRACTWaste and residuals are undeniably part of the human society. The accumulation of these materials and the “throw away” philosophy results in many environmental and health issues and safety hazard problems prevent sustainable development in terms of resource recovery and recycling of waste materials. The carbon sources in the waste can be converted to energy (electricity) using different technologies including co...

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 ca...

MACHINE COMPONENT DESIGN

DEFINITION OF A KEY  A key is a piece of steel in inserted between the shaft and a hub of the pulley or the gear, mainly to that power. Key are always inserted parallet to the shaft axis. They are need as temporally fastening and are subjected to considerable cursing and shearing stresses.  A key - way in a slut or recess in the shaft and hub of a pulley to accommodate a key. KEYS A key is a machine member employed at the interface of a pair of mating male and female circ...

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 ...

DESIGN AND FABRICATION OF MINI COPULA FURNACE AND AN ATOMIZER FOR THE PRODUCTION OF POWDERED METAL FROM WASTE ALUMINIUM CANS

ABSTRACTThis 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 a...

Design And Construction Of A Car Door Using Fibre Reinforced Plastic Composite

ABSTRACTAmong various efforts pursued to produce fuel efficient vehicles, light weight engineering (i.e. the use of low-density structurally-efficient materials, the application of advanced manufacturing and joining technologies and the design of highly-integrated, multi-functional components/sub-assemblies) plays a prominent role. In the present work, a composite automotive design methodology has been presented and subsequently applied to the development and assembly of the inner and outer s...

DESIGN AND CONSTRUCT A MULTIREMOTE CONTROLLER USING INFRA-RED MODE OF TRANSMISSION

ABSTRACTMicrocontroller based remote control system is a project design of a system that uses infra red transmission and reception principle to switch on or off other appliances. It is a wireless mode of switching appliances to a desired state. When a number is pressed in the transmitter section, the receiver section decodes the signal and utilizes it in controlling the desired appliances.Several functional blocks of circuit are put together to ensure that the design works as the designer int...

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, w...

DESIGN AND IMPLEMENTATION OF BIOMETRIC FEATURES PRE-PROCESSING

The need for identification leads to the study of biometrics. Over the ages, human beings have been identified by various means, such as the Name, Complexion, Nationality, and even some uniquely assigned codes. Of all these methods, none can be used to uniquely identify an individual distinctly under all circumstances. However, research has shown that an individual‟s biometric feature can be used to uniquely identify them, under all circumstances. For these biometric features to be appropri...

SELECTION OF WATER PUMPS

ABSTRACTThe aim of this project is to capture the utilization of pumps for various uses and to maximize the principle of selection of water pumps through the application and pump selection for specific uses our society will transformed wholestically to an industrious nation in the clean water supply for supply for domestic, industrial and down stream sector. Pump parameters and selection are analyzed categorically to enable a good conception in practical.  Centrifugal pumps can also b...

DESIGN AND CONSTRUCTION OF MOTORISED WHEEL BARROW

ABSTRACTWhen it comes to construction projects, landscaping work, and gardening, you need the right kind of equipment to finish tasks speedily and easily. One piece of equipment you would need is a motorised wheelbarrow. This is intended to carry bulky materials and heavy loads. 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 wi...

CONSTRUCTION OF INDUSTRIAL WHEEL BARROW

ABSTRACTWheelbarrow is a simple machine, which belong to the second-class lever. This is because the load or resistance is placed between the effort and the fulcrum. It is used in many areas of work to convey loads that are too heavy or bulky to be carried by hand. Wheelbarrow can be used as farm equipment, industrial equipment among others.However, the efficiency of the wheelbarrow depends on the materials used for the construction. A wrong choice of these materials can reduce the efficiency...
