INTRODUCTION In today’s quest for electrical energy and increasing hazards in our environment, alternatives to the use of non – renewable and polluting fossil fuels have to be investigated. One such alternative is SOLAR ENERGY. Solar energy is quite simply, the energy produced directly from the sun and collected elsewhere, on earth. The sun creates its energy through a thermonuclear process that converts about 650,000,000 tons of hydrogen to helium every second. The process creates heat...
INTRODUCTION The word “Train” comes from the old French word trahiner, also from the latin word trahere which simply means “pull or draw”. It is a form of rail transport consisting of series of vehicles (coaches) propelled along a fixed rail track to transport goods or passengers. It can also be defined as a private or public conveyance system that travels along fixed routes and takes up set down passengers and their luggage at fixed points. A railway station also referred to as a tr...
ABSTRACT The working principles of a window air conditioning system was described with the mode of operationg of the refrigeration cycle and its construcion. The aim of every window Air conditioning system is to achieve cooling. Change of temperature system were discussed with the methods of improving the performance of th window Air Conditioning Unit for better efficiency. This work simply explains how the performance of the window Air Conditioning system can be improved and why it i...
ABSTRACT The project work Rehabilitation and Repair of A Window Unit Air Conditioner exposes us to the internal working mechanism of the window unit a.c. The working principles component unit, faults and effective repairs carried out to ensure the serviceability of the broken down unit. It buttress the need for routine maintenance, and effective repair works to be carried out on the a.c unit as well as other electrical gadget to ensure long service life and efficiency of the required system...
ABSTRACT In this project, three (3) alternative design solutions were considered for the camp-bed. The authors utilize the local raw materials (with cost consideration) for the comments. The merits and demerits of each of the alternative with respect to the considered grip were also discussed and the solutions of the alternatives that best satisfied the limitations were selection, design and cost analysis, production process and operations maintenance and problem encountered during the de...
ABSTRACT It is proposed to design a process plant that will control nitrogen oxide emission from a plant that is producing 90wt% nitric acid of 30,000 tonnes of nitric acid. This capacity is based on 8000hours of operation per year i.e. 330 days. It is proposed that this plant will be located in any location where there is substantial release of nitrogen oxides. The process plant will control about 90% of the nitrogen oxides being emitted from the nitric acid plant. The controller which is ...
ABSTRACT Conveying goods from one place to another via trucks has been a long-held practice because of its usefulness. There are different types of trucks that are available in this regard such as ; two axle, three axle, four axle trucks etc and each with its unique functionality.Businesses relying on the movement of bulky raw materials and finished goods regardless of the distance no doubt require a truck to ease this task.In line with this challenge, it is desired to design and construct a...
ABSTRACT During forging or furnace operation, air is the utility that should be available at all time in order to ensure a smooth and standardized operation. Supplying air manually will reduce productivity and more man hour to accomplish a given task. Thus, an electric blower was designed in this regard with an efficient electric motor as the driver. The suction conditions and other application data are appropriately used to calculate the design parameters such as: suction specific speed, t...
ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with sen...
ABSTRACT The purpose of this research work is to design, fabricate and install a hydraulic brake system on a wheel system of an agricultural tipping truck. For an efficient functioning of the brake system some measures have to be strictly considered; the weight of the vehicle and the external load.The engineering materials used in the fabrication of the wheels system include metals, ceramics and polymerics.Despite the efficiency of the brake there must be routine checks and maintenance to ens...
ABSTRACT Plastic and Rubber materials have become the corner stone of our lives, so it leads to generation of huge quantity of waste. These waste materials are either mixed with municipal solid waste or dumped in an open area leading to increase in the area covered under waste land. Plastic and rubber waste, if not recycled is either land filled or incinerated, where both of them prove to be a disaster to environment. Incineration leads to air pollution whereas dumping the waste in open areas...
ABSTRACT In recent times, most of the household appliances are using electric power and as such, electricity shortage has become a major problem throughout the world. Ceiling fan is one of such appliances that consume electric power. The best way to minimize the power consumption of the ceiling fan is to reduce the weight of the ceiling fan blade. Thus, this project work entails the design of a new ceiling fan blade in which case the weight and power consumption was compared to the Panasonic...
ABSTRACT Packaging 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 dev...

ABSTRACT Wheelbarrow 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 efficien...
