ABSTRACT The kinetics and optimization of inhibitive action of leaves extract of pawpaw, Azadirachta indica (neem tree) and bitter leaf on corrosion of mild steel in acidic medium was studied by weight loss technique using central composite design of response surface methodology for optimization. The metal was analyzed using Atomic Absorption Spectrophotometer to determine its elemental compositions. The extract was obtained by liquid extraction using ethanol and was analyzed to determine ...
ABSTRACT The Project work presents an Optimum design of welded plate girder. A simply supported plate girder with span of 15meters was chosen for the case study. The girder was subjected to a self-weight of 50KN/m and concentrated loads of 1000KN at 5m and 10m from the left support. The plate girder was analysed to get the design moments and shear forces. An initial manual design was carried out for the plate girder in accordance with BS 5950-2000. From the design, initial section parameters ...
ABSTRACT Nowadays, the destruction and pollution of humane environment has produced an ever growing awareness worldwide of the need for more effective sedimentation processes. The main aim of this project was to design and fabricate an experimental sedimentation rig with the objective to determine the rate of settling against time using calcium carbonate as a test sample.The rig consists mainly of the cylindrical tank, valves, motor, stirrer, and the sight glass. For the test run, 82 litres o...

ABSTRACT This project deals with the design and development of restaurant order meal system, in order to reduce the number of staff. In meal ordering project, you can request for any kind of food or drinks available in the restaurant which contains the menu embedded in each button. Microcontroller is the central processing unit CPU of this project and it also consists of Bluetooth it is said to be the main component used in this project. Microcontroller gets the coordinates from the Bluetooth...
Abstract The project DESIGN AND CONSTRUCTION OF A 20-METRE DISTANCE REMOTELY CONTROLLED METAL DETECTOR is used for detecting metallic objects such as phones, bombs, and other metallic objects that are hidden from view. The design is based on the principle of the Resonant Frequency Oscillator (RFO) metal detectors in which oscillation is a function of parallel connection of an inductor and a capacitor operating in resonance. The project is divided into two sections. The transmit...
The energy sector plays a major role in driving Kenya’s economy. The need to conceive, develop and sustain energy generating sources cannot be underestimated. Being a growing economy, Kenya therefore needs to redirect her effort in production of self-sustaining energy generating sources. It is in this line that the government through the ministry of industrialization, energy and vision 2030 sought to establish the Numerical Machine Complex, which serves as a hub for fabrication, assembl...
ABSTRACT Maize, known in many English-speaking countries as corn, is a grain domesticated by indigenous people in prehistoric times. The Aztecs and Mayans cultivated it in numerous varieties throughout central and southern Mexico, to cook or grind in a process called nixtamalization. The crop spread throughout America and later around the 1250 BC it spread to all corners of the region. Any significant or dense populations in the region developed a great trade network based on surplus and var...
This project is based on the design and construction of a Wireless Electronic Notice Board. It can be widely used to display latest information anywhere such as institutions, shop, place of worship and other places. This Wireless Electronic Notice Board will offer flexibility to user to control the information display within 50m to 200m range. Similar works were reviewed and the draw backs of these projects were cited and their advantage also considered. The design of the Wireless Elec...
ABSTRACT Breadfruit (Treculia Africana) or simply breadnut is very important both as food and as a potential source of oil. The economic importance of this tropical seed on domestic and commercial basis has necessitated the development of a pedal breadfruit dehuller, that would reduce the Cost of maintaining and purchasing motorized dehuller, Solve the problem of fuel scarcity, inadequate electricity supply . In the engineering design of this machine, the action zone consisted esse...
This project work aims at formulating Scheffe’s mathematical model which prescribes concrete mix ratios for a desired compressive strength of periwinkle shell aggregate concrete and obtaining the combination of water, cement, river sand and periwinkle shell which will produce the optimum strength.The model was formulated from first principle producing an equation with several unknown coefficients. These coefficients were determined by carrying out compressive strength test on thirty c...

ABSTRACT The objective of the work is the catalytic conversion of waste plastics into fuel oil and solid wax using Ca(OH)2 and the design of pyrolysis reactor. Plastic wastes such as, polypropylene, low density polyethylene, high density polyethylene, polystyrene are the most frequently used in everyday activities and disposed of to the environment after service. There are a number of methods by which plastic wastes can be managed such as incineration, recycling, land filling, thermal and cat...
