The effect of rainfall on the quality of hand dug well water

                   ABSTRACTThis study investigated the effect of rainfall on the physical, chemical and bacteriological quality of some selected hand-dug well water consumed by students of Ekiti State University, Ado-Ekiti. To this effect, six (6) samples from three (3) hand-dug well used, labeled (Ab, Bb, Cb & Aa, Ba, Ca) indicating before and after rainfall respectively were collected and examined for both the bacteriological and physio-chemical parameters. The bacteriological...

ASSESSING HEAVY METAL CONCENTRATION IN SOIL OF FABRIC PRODUCTION VICINITY

ABSTRACT The study of heavy metal deposition and accumulation in fabric production vicinity is of increasing interest because of the awareness that heavy metals present in soils may have negative consequences on human health and the environment. This study describes the assessment of heavy metal concentration in soils of fabric production vicinity a case study of Itoku Adire Kampala market, Abeokuta, Ogun State, Nigeria. Five (5) top soil samples and 5 sub soil samples were colle...

Bearing Capacity and Settlement Characteristics of Soil: A case study of FUTO Senate Building & FUTO NDDC Hostel Area, Owerri, Imo State.

The sole purpose of this project work is to determine the settlement characteristics of soil for the construction of building, a case study at FUTO Senate Building  area  and FUTO NDDC hostel area, other objectives are the classification of the  soil, determination of the strength properties of these soils and also making of  sundry recommendations about the type of foundation most suitable for the  construction of buildings on these soils. Soil samples were collected from FUTO  Sen...

Corrosion Studies of Mild Steel in Biodiesel Obtained from Ghee Butter (Mann Shanu)

It is of no doubt that one day, fossil fuels, which the whole world highly depends on, will come to a halt in a few decades to come. To this reason, researches have been geared towards alternative sources of energy: biodiesel, a form of renewable energy (energy that can be regenerated once used up), is one that has been made known and being tested in some parts of the world. Due to the fact that biodiesel is hygroscopic (absorbs water readily from the atmosphere), as well as other fact...

Simulated Design for the Removal & Recycling of Acid Gases from Natural Gas

Natural gas is one of the major sources of fuel and raw material to industries all over the world. However, it contains some acid gases such as CO2 and H2S which are corrosive and harmful to the environment. These acid gases must be brought to permissible limits to promote safety in the operation and increase the heating value of the natural gas. In this project, we design an acid gas removal plant based on the amine treatment process using ASPEN HYSYS software.     ...

BASIC LUBRICATION PRINCIPLE

This write-up gives an overview of lubrication, lubricants, their types and general properties, and the principles of lubricant application. It further emphasizes on the different methods of lubricant application, specification, selection and storage.

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...
