CONSTRUCTION OF INDUSTRIAL WHEEL BARROW

ABSTRACTWheelbarrow is a simple machine, which belong to the second-class lever. This is because the load or resistance is placed between the effort and the fulcrum. It is used in many areas of work to convey loads that are too heavy or bulky to be carried by hand. Wheelbarrow can be used as farm equipment, industrial equipment among others.However, the efficiency of the wheelbarrow depends on the materials used for the construction. A wrong choice of these materials can reduce the efficiency...

MACHINE TOOL CONTROL

INTRODUCTION  The purpose of a control system is to produce a desired output. This output is usually specified by a command input, and is often a function of time. For simple applications in well structured situations, to control, and the controller must have the capability of reacting to disturbance, changes in its environment, and new input commands. The keys element that allows a control system to do this is feedback, which is the process by which a system’s output is used to influ...

PARAMETRIC PERFORMANCE EVALUATION OF A WINDOW UNIT AIR-CONDITIONER AND ITS MAINTENANCE

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 improv...

GEAR DESIGN AND TYPES. (7D)

INTRODUCTIONEach machine consists in principle of three basic parts: a motor or another prime mover (that sets the machine in motion), an actuating mechanism (which is directly doing the needed work:digs a ditch, weaves cloth, peels potatoes, propels a ship, and so on), and a transmission that connects the first two parts. Sometimes, the transmission may be lacking, for example, in a fan the impeller is mounted  directly on the shaft of the electric motor. But in most cases, the transmis...

DESIGN AND IMPLEMENTATION OF A COMPUTERIZED MODERN POULTRY FARM A CASE STUDY IMO POULTRY FARM LTD

ABSTRACT The magical impact of computer has made enormous contribution to all aspect of the society people can now do things easily unlike in the past. Computers have lesson human activities (effort) in their day to day life, by reducing both human labour and time in solving their problem which are both numerous / unlimited. The introduction of the magical machine has led to the further growth of Agricultural products. The technological know how and scientific research reveals that a lot ...

DESIGN AND IMPLEMENTATION OF AN ON-LINE VOTING SYSTEM (A CASE STUDY OF ENSIEC ENUGU)

ABSTRACTVoting is a very important process in the Nigerian political system.  It is one of the means and most effective method of ensuring a legitimate government through popular participation.  To enthrone sound democracy and stability in the political system of the Enugu state a system of rig-free voting has to be put in place.The system would among others discourage double voting, forgery or hoarding of electoral materials massive transfer of ballot papers destruction of ballot b...

EQUIPMENT DESIGN PROJECT ON DESIGN AN INVERTER FOR THE PRODUCTION OF 100000 METRIC TONES PER YEAR OF ETHANOL FROM SUGAR CANE

ABSTRACTAn equipment design project was carried out to design an inverter (Bioreator) or the production of 100,00 metric tones per year of ethanol from sugar cane.An inverter is a part of process equipment used in ethanol production from sugar cane.  While the rest process equipment include crusher, filter, centrifuge, fermented, distribution column and dehydrator.Having based on design on a steady –stated operation, the required feed rate and enthalpy in the inverter, calculated from ...

DESIGN AND IMPLEMENTATION OF AN AUTOMATED MOTOR VEHICLE DRIVER’S LICENSING SYSTEM. (A CASE STUDY OF ENUGU MOTOR LICENSE OFFICE, ENUGU STATE; ABAKPA) NIKE).

ABSTRACTThe ill treatment that take place in our motor vehicle Drivers licensing office today, one have to wait endlessly in order to get his driver’s licensing or renew his driver license and so on. This is a problem that is experienced daily, which robs the government a huge sum of money through fraudulent means.  Being a system run manually, it is prone to many man-made errors both intentionally and unintentionally, which could be unnecessary delays in attending to customers due to...

EVALUATION OF THE EFFECTS OF ANTHROPOENIC ACTIVITIES AND DOMESTIC WASTE ON SURFACE WATER QUALITY (A CASE STUDY OF EKULU RIVER, ENUGU).

ABSTRACTThe microbiological and organic pollutants characteristics of umuosoko stream in ikwuano local government area, Enugu state, Nigeria were carried out. Twenty water samples were collected from four different parts of the river.  The pour plate technique was employed for the isolation of micro-organisms. Colonial morphology, Gram staining and biochemical tests were used for identification and characterization. The statistical analyses used were analysis of variance and standard dev...

EVALUATION OF THE EFFECTS OF FLOODING ON THREE VARIETIES OF RICE (A CASE STUDY OF ABAKALIKI, EBONYI STATE)

ABSTRACTFlooding has been described as one of the most important environmental factors determining the distribution of salt marsh plants. We studied the impact of five water levels on the germination and establishment of the invasive cord-grass spartina deniflora. Plant house experiment was carried out to determine the effects of time and depth of flooding on the survival and growth of rice. Data showed that time and depth of flooding had significant effects on the survival and growth of rice...

THE DESIGN AND FABRICATION OF A PRESSURIZED KEROSENE OVEN (60 X 90)

ABSTRACTIt views of the smoke released when using a firewood for baking cakes, bread, preserve fresh fishes and warming or remove ice form frozen food by some mothers at home, restaurant, fast food shops etc.We discovered the need to design and fabricated kerosene pressurized Oven that will reduce the amount of smoke emitting into the atmosphere and improve the quality of baked food in the society.Kerosine pressurized oven will prevent  unnecessary heat from harming the users and lime wa...

ASSESSMENT OF CARBON MONOXIDE (CO) LEVEL IN ENUGU METROPOLIS MONITORING INDUSTRIAL AND RESIDENTIAL AREA

ABSTRACTAir pollutions pollutant showed that the extent of spreading depends on the motor vehicle traffic population of the area. This pollution strongly generated through combustion of fossil fuels presents difficult environmental challenge to societies as it could degrade the environment and affect human health and quality of life. Vehicular emissions are major contributors to air pollution in urban areas as they contain harmful gases. The levels of carbon monoxide has been investigated in ...

DESIGN THE ABSORBER (SCRUBBER) IN THE PROCESS PLANT FOR THE PRODUCTION OF 100,000 METRIC TONNES/ YEAR OF ETHANOL FROM DIRECT HYDRATION OF ETHYLENE

ABSTRACTThe general approach to any design of a process plant involve an advanced network of chemical engineering process.Absorber is a process plant or equipment that are used in the purification of gas or separation of unwanted gas from the mixture when it comes in contact with the liquid. In this models mass transfer reaction and equilibrium process as they prevail in conventional tray absorbers and in cascade of trickle bed reactors are incorporated. Owring to the mass transfer characteri...
