QUALITY ASSESSMENT OF DRINKING WATER SOURCES (STUDY OF OLOWOTEDO COMMUNITY, OGUN STATE)

ABSTRACTThe study aimed to assess the quality of drinking water in Olowotedo community of Ogun state, Nigeria. Five samples were taken from different sources (wells, borehole, tap and sachet water) were analyzed, Selection of water samples was carried out using proportionate allocation, equal allocation, simple random sampling  and systematic sampling methods depending on the stage. The water  quality parameters examined and their results for all the five water samples were; colour having 0...

Energy Audit, Optimisation and Management of Liquefied Natural Gas Plants with Renewable Energy Resources Around the Plant: A Case Study of Brass LNG, Brass Island, Nigeria

The energy generation and power consuming loads at Brass LNG facility located in Brass Island, Bayelsa State Nigeria were analyzed and compared with expected demand changes and means of minimizing cost and greenhouse gas emission were also proffered with wind and solar energy penetration into the overall power mix . The wind and solar hybrid power generation system reduced the fuel consumption, greenhouse gas emission and noise pollution by the generators and turbine by relieving some o...

EFFECTIVENESS OF PORTSMOUTH HIGHWAYS PRIVATE FINANCE INITIATIVES (PFI) SCHEME

Since the inception of the Private Finance Initiatives (PFI) in the United Kingdom, Government are increasingly adopting it as a means of proving infrastructure to the public neglecting the traditional procurement methods which relies completely on the public finance. Private Finance Initiative (PFI) is a method of contract procurement where the private organisation provides an infrastructure, finances, operates and maintains the infrastructure. This is done by transferring the risks involved...

THE CONSTRUCTION OF A 2KVA AUTOMATIC VOLTAGE REGULATOR

ABSTRACTThe AVR is automatic voltage regulator and it is a device which is used to regulate or stabilize electrical power supply for electrical or electronic appliances       In this project, therefore, we are interested in the construction of this all important device. Furthermore, we shall discuss the techniques, processes, switching stages and then the working principle of the automatic voltage regulator       Chapter one o...

THE CONSTRUCTION OF AUTOMATIC VOLTAGE INVERTER AND A BATTERY CHARGER

ABSTRACT Automatic voltage inverter is an important area in power system engineering.  It is the process of using a 12v DC from the battery to achieve a 220/230V AC through the help of oscillator, drivers, power transistors and transformer.  The stages are battery to oscillators, oscillators to drivers, drivers to power transistors then from power transistors to transformer which is capable of giving out 220/230V (1000w) as an output.   A 1.25KVA (1000w) voltage...

SIMULATION OF REACTIVE POWER CONTROL IN AC TRANSMISSION SYSTEMS USING STATIC VAR COMPENSATOR

Voltage stability is a major concern when planning and operating electrical power systems. As demand for electric power increases, power systems are stressed more and more.  Since the construction of new transmission lines is very expensive, and the right of way requirements are not easy to come by, a cost-effective policy is to use the existing lines to their maximum thermal and stability limits, and this requires optimum sharing of power flow in the system. Flexible AC Transmission S...

DESIGN OF 2TONNES AUTOMATED HYDRAULIC JACK

ABSTRACTThe design of 2 tones automated hydraulic jack was carried out using the basic principles of machine design and analysis. The hydraulic jack was designed with a 204watts wiper motor with the output lever having a torque of 30Nm.  The effective diameters of ram and plunger pistons were found to be 12mm and 6mm respectively, when the load lifted was 2000N with mechanical advantage being 3.4. The working stress was 21MPa when the effort applied at the handle by the lever w...

SUSTAINABLE E-LEARNING FOR NIGERIAN EDUCATIONAL DEVELOPMENT

ABSTRACTAs Nigeria aims at optimizing the implementation of the E-learning programme in tertiary institutions, this paper discusses the ways by which the implemented E-learning can be sustained. The discussion was carried out using data derived from students, teaching staff and telecommunication engineers in Nigeria using Owerri metropolis as a case study. Data analysis was carried out and analyzed using excel and Minitab. Conclusions and recommendations were drawn for effective imp...

PRESSURE TRANSIENT ANALYSIS IN GAS RESERVOIRS (PSEUDOPRESSURE APPROACH - A NEW APPROACH)

The ability to analyse the performance and forecast the production of gas wells is important in gas reservoir engineering. Information like the reservoir permeability, damage and improvement, reservoir pressure etc should not be faulty because when faulty, estimation of information that involved them will also be faulty which will in turn depicts wrong forecast of the gas well. To obtain a reasonable degree of accuracy, different analytical methods have been studied and applied to mode...

THE IMPERATIVE OF ENGAGING PROFESSIONAL BUILDERS IN BUILDING CONSTRUCTION WORKS

Time has come for people to know the implications of engaging non-professional builders in building construction works. The stoppage of engaging non-professional  builders would reduce or even stop  the event such as shoddy works, use of inappropriate materials/personnel’s and abandonment of project, cost overrun, and inadequate supervision/incompetence and incessant collapse of buildings. This project therefore delved into the imperative of engaging professional builders in build...

Energetic and Exergetic analysis of waste heat recovery system in sulphur acid using organic Rankine cycle.

The continuous search for sustainable alternative energy to non renewable energy to mitigate environmental pollution has made waste heat recovery from industries process, material and energy streams frontier. Power plant technologies like steam and Organic Rankine cycle are been research by researchers to improve waste heat recovery efficiency and energy utilization. In this study Hexane and Toluene are the organic fluid used .Their performance inwaste heat recovery in the melting furnace...

Evaluation of Guinea Corn Husk Ash As Oil-Well Cement Slurry Extender

The objective of primary cementing operation is to provide zonal isolation while drilling oil and gas wells. To achieve this purpose, cement slurries are designed by adding additives to control certain properties such as density, free fluid, compressive strength, rheology, among others. These additives are imported whereas Ghana produces large amount of agro-waste yearly causing environmental nuisance, though these have the potentials of being used in the petroleum industry. The extend...
