CONSTRUCTION OF AUTOMATIC WATER LEVEL CONTROLLER FOR BOTH OVERHEAD AND UNDERGROUND TANKS

ABSTRACTAutomatic water level controller for both overhead and underground tank is designed to monitor the level of water in a tank. It displays the level of water and when it is at the lowest level; a pump is activated automatically to refill the tank. When the tank is filled to its maximum capacity, the pump is automatically de-energized. Several circuits are put together to ensure proper working of this design, and the block diagram includes the supply unit, the micro-processor unit, the s...

Construction Of Metal Sharpening And Dulling Device

ABSTRACT As  a result of modern development in Science and Technology, most of the large scale industrial used machine were now modernized to simple small and efficient machines. Some of these machines were either operated manually or the aid of electricity. For this reason, big metal sharpening machine was here reduced to simple term, which can be operated manually such as file and grinding machine for production firms and homes.  This machine performs the same functions ...

THE COMPARATIVE ANALYSIS OF THE STRENGTH OF CONCRETE MADE FROM VARIOUS AGGREGATE

ABSTRACTThe work has gone a long way in determining strength of concrete made of various aggregates such as granites stone, black gravel, washed gravel and surface gravel.Some factors such as porosity of the  aggregate temperature coursing lose of water plate form for mixing of concrete mix affect the workability and eventually the strength of concrete.This project work consist of using hydraulic machine to carryout the compressive test of the strength of concrete made of the earlier men...

Fundamental Principles Of Drying

INTRODUCTIONThe separation operation of drying converts a solid, semi-solid or liquid feedstock into a solid product by evaporation of the liquid into a vapor phase via application of heat. In the special case of freeze drying, which takes place below the triple point of the liquid being removed, drying occurs by sublimation of the solid phase directly into the vapor phase. This definition thus excludes conversion of a liquid phase into a concentrated liquid phase (evaporation), mechanical de...

REPAIR AND REHABILITATION OF A FAULTY DEEP FREEZER IN THE MECHANICAL ENGINEERING DEPARTMENT

ABSTRACT Mechanical Engineering Department of the named Institute has many non – operational malhiues. Sequel to the fact, maintenance was poorly excuted which resulted to the breakdown deep freezer.Quality and effectiveness of machine maintenance were well observed. Also, a minimized maintenance and a highly successful  repair was adopted.In other words during the repair and rehabilitation of the facility Deep Freezer, appropriate tools, cost and  quality of materials were w...

ANALYSIS AND DESIGN OF A RETAINING WALL

INTRODUCTIONRetaining walls are structures used  in providing stability for earth or materials where conditions dis allow the materials from summing its nature al slope or stabilityThere are many factors affecting or militating against the stability of retaining walls. These includes the level of water table behind the wall, size of the base of the wall and nature of the soil retainedUnder these effects of he nature of soil,. we have the angle of internal content between the particles, t...

Design of a Biogas Plant

Note: This work contains only the schematic diagram/design of a biogas plantBiogas typically refers to a mixture of gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from regionally available raw materials such as recycled waste. It is a renewable energy source and in many cases exerts a very small carbon footprint.Biogas is produced by anaerobic digestion with anaerobic bacteria or fermentation of biodegradable materials such as manure, s...

THE BLEACHING OF PALM OIL USING ACTIVATED CHARCOAL

ABSTRACTThis project work is on the bleaching of palm oil using activated charcoal.The charcoal used for this work was made from pieces of animal bone by carbonization method.  It was then activated into two different samples.  Firstly, the basic sample was activated using anaphoric acid (H2 s04) while the other was activated by just heating as a control for the experiment; both at a constant temperature of 5000c and approximate time of 2hours.They were both size reduced into fines ...

COMPARATIVE ANALYSIS OF THE STRENGTH OF CONCRETE MADE FROM VARIOUS AGGREGATE

INTRODUCTIONThis work was obligated to present in one. The fundamental and practical information in the filed of the comparative analysis of the strength of concrete made from various aggregate which may be useful to people involve in civil and structural engineering and particularly, those that found pleasure in the design and related structure.Due to high cost of sand in the market the  comparative analysis of strength of concrete  made from various aggregate play an important rol...

CONSTRUCTION OF A STELL CUPBOARD

ABSTRACT The aim of this project was to construct a steel cupboard in order to help us acquire the knowledge of fabrication of a modern cupboard and the essence of it. Also to enable us (the students of chemical Engineering) to know how to construct as future engineers. The construction of steel cupboard was done using a square pipe of 1.5mm thickness and the mild steel having a thickness of 1.5mm. it was mark out cut, welded, filled and painted. The  cupboard has length and height of ...

DESIGN AND CONSTRUCTION OF FOUR-WAY TRAFFIC LIGHT

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 ...

PRODUCTION OF DOMESTIC POWDER

ABSTRACTThis research project is aimed at producing domestic powder and consequently, three different types of powder were produced, namely, simple face powder (pan-cake), medicated/Antiseptic powder (dristing   powder).During the various production Talcum, Zinc-oxide, Perfume, Menthol, Tragasan 300 DP (Triclosan), Mineral oil and colour (brown) were the materials used in the production of different powders. And equipment and apparatus used for production  of the three different pow...

CONSTRUCTION OF A HYDROCYCLONE

ABSTRACTThe hydrocyclone is a separating device used for the separation of dust particles from air, which has no moving component parts. This mechanism can also be defined as a system of winds circulating about a center of relatively low barometric pressure and on the earths surface, blowing inward in spiral form.This project is constructed for the separation of liquid – liquid and solid – liquid mixture, like air and dust mixture, dust and liquid drop. This equipment is constructed to se...

CONSTRUCTION OF WATER STORAGE TANK (2000 LITRES)

ABSTRACTThe 20000 liters storage tank was constructed for effective storage and conservation of third with three (3) mild steel sheet of 14 gauge (2mm) thickness. The construction started by marketing out 1½ (One and half) mild steel of 2440 Mm by 113Mmusing metal meter rule and critter the already market out dimension underwent cutting with a backsaw and after marking out and cutting operation of the cylindrical part it under went fording, using hammer and folding machine, and finally ...

REFINING OF VEGETABLE OIL WITH ENUGU COAL

ABSTRACTThis project was carried out using acid activated coal from Enugu coal and the production of ve4getablew oil was monitored using spectrophotometer to measure the absorbance. It was also perform to check the suitability of activated Enugu coal as a bleaching agent for palm oil.The Enugu coal samples were collected, size reduced, carbonized and activated with acid (phosphoric Acid) before being used for the bleaching process. The bleaching process lasted for 40minutes and it was absorbe...
