DESIGN AND CONSTRUCTION OF ELECTRIC BLOWER FOR FORGE OR FURNACE

ABSTRACTDuring 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, ...

Design and Performance Evaluation of a Waste water Treatment Plant.

The study aimed at the design, construction and performance evaluation of a model domestic wastewater treatment plant was carried out. The treatment unit was a Waste Stabilization Pond (WSP) comprised of one facultative pond, three maturation ponds, and a contact filtration unit, all in series. The effluent of the WSP, after filtration through clay media, had the BOD reduced to 15.4mg/l, from 356mg/L indicating a 95.67% removal level. A Faecal Coliform (FC) count of the influent sample gave 1...

Design Construction and Performance Evaluation of a Model Waste Stabilization Pond

The study aimed at the design, construction and performance evaluation of a model Waste Stabilization Pond (WSP). The WSP comprised of one facultative pond and three maturation ponds all in series. The influent of the WSP after filtration through the lined sandy loam media (obtained from the premises of Federal University of Technology, Owerri, Nigeria) had the BOD reduced to 22 mg/L from 356 mg/L indicating a 93.8% removal level. A faecal coli form count (fc) of the influent sample gave 1×1...

Design and Construction of a Manual Chips Packaging Machine

ABSTRACTPackaging 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 ...

INDUSTRIAL POLLUTION AND GREEN HOUSE EFFECT

ABSTRACT The  title  of this  research  work’s  industrial pollution  and  green  house  effect”  The  purity of the  atmosphere  and  the  environment  can  be  impaired  by  the  industrial  effluents  or  sewages.  Poisonous  compound  like  organic  and  inorganic material , the  consequence of  toxic  inhalants  s...

Design and Fabrication of Ceiling Fan Blade

ABSTRACTIn 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 m...

SOAP PRODUCTION

ABSTRACTThe aim of this seminar is soap production. Due to societal demands on cleaning agent to promote her hygienic conditions leads to research on how to produce soap which is one of the cleaning agent to meet the demands. Also in order to earn living through the out-come (financially) from the soap produced , many life can be enriched in the society. The process of soap production include”: cold process and hot process. The cold process of soap production requires measurement of lye a...

THE DESIGN OF A MODERN RAILWAY STATION

INTRODUCTIONThe 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 train...

USE OF SOLAR ENERGY RATHER THAN ELECTRIC ENERGY TO CHARGE CELL PHONE

INTRODUCTIONIn 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 he...

CONSTRUCTION OF PORTABLE WHEEL-BARROW

DESIGN AND CONSTRUCTION OF 1000VA POWER INVERTER SYSTEM

ABSTRACT As the name of the project implies “Power Inverter”, is an electronics system that converts DC Energy (voltage) to an AC energy.  The major aim of this project is to design and construct a 1000VA Power inverter that is capable of powering loads of equivalent ratings, in the absence of power supply from NEPA or Generator. The system (power inverter) consists of the AC mains sensor section, Relay/change over section, Battery charger section, oscillator section, Driver sectio...

THE ROLE OF CHEMICAL ENGINEERS IN THE SOCIETY

ABSTACTMost of the critical condition societal problem such as conversion, storage and transportation of energy resources, food processing, preservation and supply, natural resources, development and recovery, their processing to final product, environmental quality control etc.hinge or the creative application of che- ical engineering. This led to the question “The role of chemical engineers in the society The net result is the persistent recruitment of other professionals by industri...

DESIGN AND CONSTRUCTION OF AUTOMATIC EMERGENCY LIGHT

ABSTRACTAs the name of the project implies “Automatic Emergency Light” is an electronic system that can provide light during emergency situations i.e when mains (NEPA) supply fails.  This system can provide enough light with full brightness in a given room or office.   The system makes use of white light emitting diodes for the lightings.  It is automatic in operation, in the sense that it can switch itself off when the battery charges full. Automatic Emergency light compr...

FORMULATION AND PRODUCTION OF LEVERA SOAP

ABSTRACTThe production of the soap was carried out using all the necessary equipments like the reactor, mould, stirrer, hygrometer guage etc. and all the required reagents for soap production in correct proportion.In the production, palm kernel oil (P.K.O) was used instead of tallow or grease.  This was because soap produced from grease or tallow tends to dissolve slowly at room temperature, whereas, soap of palm kernel oil product gives a quicker lather which is relatively suitable.Diff...

DESIGN AND CONSTRUCTION OF PUBLIC ADDRESS SYSTEM

INTRODUCTIONA public address system is an electronics sound amplification and distribution system with a microphone, amplifier and loud speaker used to allow a person to address a large public. The public address system consists of three main parts namely, the microphone (input transducer), amplifier and the loudspeaker (output transducer).The microphone picks up the sound and convert it to electronic signal in milivolts and this is fed to the amplifier for amplification. In this project, a d...
