A lawnmower is a machine that uses a revolving blade or blades to cut a lawn grass. Many designs have been made, each suited to a particular purpose. Manual grass cutter has environmental issues regarding pollution's and also require the need of man power to operate and has a great maintenance to its engine. This robot is design to be environment friendly and operated by a rechargeable battery and can be describe as an intelligent robot because the micro-controller receives information from s...
ABSTRACT: This project work is on the development of a solar powered car. It involves the design and fabrication of a solar powered car with a carrying capacity of two and a maximum speed of 30 km/hr, which runs entirely on a stand-alone solar system. The car is a unique prototype sedan car. It is designed with dimensions of 3 meters’ x 1.6 meters'. The maximum load carrying capacity of the vehicle is 700 kg and it requires a driving force of about 4.3 kW. The solar car uses a clean engine...
Due to the need for recycling Polyethylene terephthalate (PET or PETE) materials, especially bottles because of its various uses and applications, it was necessary that a locally made machine for crushing and shredding the PET materials was fabricated. The crushing process is necessary so as to aid the transportation and workability of the material. This is a paper work for the activities carried out in the design, construction and fabrication processes.
Clean and potable water is one of the basic infrastructures any responsible government needs to provide for its people. I was part of a team of competent engineers that carried out inspection, repair and maintenance of facilities at a water treatment plant. This is a paper work for different maintenance and supervision activities carried out at the water treatment plant. I employed my engineering skills in inspection, maintenance and supervision of the machines, making sure that they are up a...
ABSTRACT This project work deals with the design and fabrication of a suitable journal bearing test apparatus which can help in visualizing the behavior of journal bearing and its characteristics, and in determining the bearing parameters such as load bearing capacity, maximum oil film temperature, viscosity of lubricant, oil film pressure, and coefficient of friction based on experimental analysis. The work covers the design of a test apparatus which can be utilized to check the behavior of...
The research study presents the development of a model for Energy cost in manufacturing industries under irregular power supply. The work considers power consumption in the operation of production machines, hence cost incurred in running of these machines Parameters such as machine types for production, numbers of machine types for production and power ratings of machines for production were also considered in the development of the model The study employs linear programming approach in formu...
THESIS ABSTRACT (ENGLISH) NAME: MUFATIU MUSILIU BELLO TITLE: Experimental and Numerical Investigations of Flow-Accelerated Corrosion Downstream Orifices MAJOR: MECHANICAL ENGINEERING DATE: 8th May, 2012 Flow-Accelerated Corrosion (FAC) is a form of corrosion that affects carbon steel or low-alloy steel piping ...
An energy audit on the Brass Liquified Natural Gas plant at Brass Island former Agip facility was carried. The average offshore windspeed and wave return periods for 12months were measured for their wind and wave energy potentials. Also, the solar insolation for the location was collected for a 12month period. A pilot design based on techno-economic analysis was made for a wind-solar- gas turbine hybrid power system and results showed it's cheaper, environmentally friend, and more efficie...
Water based metalworking fluids must be properly mixed and maintained in the proper concentration range to maximize performance. When fluid concentrate and water are mixed to charge the machine’s fluid reservoir or central system, the fluid concentration must be tested to insure that the starting concentration is correct. The concentration can be measured with a refractometer, test strips or a chemical titration method. Concentration may be expressed as a percentage or as a ratio of the am...
By definition, penetrant testing (PT) is the resurgence of a liquid (or a gas) from a discontinuity in which it had previously been introduced during a penetration operation. A logical extension of the visual examination, this method makes it possible to detect discontinuities opened to the surface of the controlled part in the form of colored or fluorescent indications, respectively observed against a white background or on a black background. PT comes in four phases, the first of which is...
Fossil fuels (coal, fuel oil and natural gas) still meet the major part of our energy demand and are getting fast depleted. Moreover, there are serious pollution hazards like greenhouse effect and global warming which occur due to fossil fuel burning. The use of nuclear power too has its own problems and nuclear fusion is yet to be realized in practice. We have thus been forced to look for non-conventional power generation systems so as to reduce fossil fuel consumption by increasing the conv...
ABSTRACT Composites have been developed with great success by the use of reinforcement. Monolithic materials cannot possess all the properties to be obtained hence, the need to employ the use of composite materials. Aluminum is generally utilized as a basic material particularly in the aerospace industry in view of its light weight property Be that as it may; the low quality and low melting point were continuously an issue.However due to these limitations, intense exploration on the use of me...
In this paper, the simplicity of the convectional Histogram in-motion mapping for obstacle avoidance technique which is now modified and modeled to Hybrid histogram in-motion mapping (HHIM) for autonomous mobile robot navigation and obstacle avoidance was primarily developed by AKWARA UCHENNA C. to solve robot navigation problems for completely unknown environment particularly for a static wave concave shaped obstacle. The developed model is to address the problem associated with a static wav...
