ABSTRACT Water is one of the most important substances on earth. All plant and animals must have water to survive. If there is no water there would be no life on earth. Disease causing germs and chemicals find their way into water supplies when this happens, the water becomes polluted. The principal objective of this research work is to asses the impurities found in domestic and industrial wastewater. Other objectives are to asses the presence and absence of organic, inorganic and micro-org...
INTRODUCTION This section briefly describes the main features of pumps and pumping systems. What are pumps and pumping systems? Pumping systems account for nearly 20% of the world’s electrical energy demand and range from 25-50% of the energy usage in certain industrial plant operations (US DOE, 2004). Pumps have two main purposes: 1. Transfer of liquid from one place to another place (e.g. water from an underground aquifer into a water storage tank) 2. Circulate liquid around a system ...
ABSTRACT The technical report presented below is based on the design of mechanism that can be used to open and shut the windows of mechanical engineering workshop from ground level .this mechanism was designed in order to improve safety and convince in their workshop .in the report, the design analysis were made and materials were selected based on operating conditions of each component. The material of the tilt and turn mechanism is cast iron while the material of the lever (handle) is stain...
ABSTRACT This research work was carried out to evaluate the different methods of corrosion prevention, control and monitoring. In the course of the research many scholarly articles on the subject matter were reviewed from which the researcher got lot information concerning the topic at hand. Thus making the research work a reliable source of information as far as facts about corrosion is concerned. To ensure this work satisfies the quality expected of it, an experiment was carried out by th...
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...
