For a volumetric gas reservoir, gas expansion (the most significant source of energy) dominates depletion behavior, and the general gas MBE is a very simple yet powerful tool for interpretation. However, in cases where other source of energy are significant enough to cause deviation from the linear behavior of the P/Z plot, a more sophisticated tool is required. For this, a more advance...
This project covers a study of the effect of seawater corrosion on 0.34% and 0.36% carbon steel compositions. Two (2) specimens (steel rods) of length 150mm (each) for both steel compositions were obtained. Out of each was gotten four (4) specimens of 10mm length, 10mm diameter and two (2) specimens of 50mm length, 10mm diameter. This yielded a total of twelve (12) samples. For each steel composition, one (1) specimen of 10mm length and one (1) specimen of 50mm length were heat trea...
ABSTRACT Whenever we think of redefined security, we think of coded electrical door lock. It is a microcontroller based security door lock that can be used in homes, offices, laboratories, etc. for more reliable and high fidelity door control system, powered by electrons panel or electromechanical panels. Due to high rate of insecurity, especially intrusion into homes and offices, this project provides the users with an electronic keypad to enter the password required to get access into home...
ABSTRACT Cell phones need electric sources to charge their batteries in order to work, but there are people in developing and third world countries that find it hard to access electric sources.In an attempt to provide an alternative means of charging to those unfortunate areas in third world and developing countries, a solar powered cell phone charging booth is to be designed and constructed in this project. The goal of this project is to create a multiple output solar cell phone chargers f...
Abstract In this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a prime mover to produce a fuel-less generator. The coupling was done using two crankshaft pulleys to match the speed of the alternator to that of the dc motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a sustainable output voltage of 232V was achieved.

Today, humanity can be classified as living in a “machine society” where technological tools are predominantly at different levels interfacing in the day–to-day activity of man. These livelihood activities constitute and deliver economic, social and political benefits and potential risks to the survivability of nations –especially developing nations like ours. Energy meter has been classified as Electromechanical Energy Meters. It is regarded as the most traditional and widely used en...
This study covers the evaluation of the synergistic effect of Datura stramonium leaves extract-Zn2+ in the corrosion inhibition of mild steel in well water. Varying effects of different concentrations of the extract and 5ppm of Zn2+ on the corrosion inhibition of the mild steel specimen will be determined in order to ascertain the synergistic effect that exists between the leaf extract and Zn2+
The availability and stability of electrical energy is necessary for domestic and industrial use. But unfortunately the monopoly which the Power holding company of Nigeria (PHCN) enjoys in this country is not in favor of the electricity users, because the supply is never constant and damages occur due to inconsistency of this supply is very enormous. However, millions of naira’s are lost every day in the commercial and industrial sectors, and even at the same time a lot of Lives are wasted ...
ABSTRACT The primary objective of this study is to identify the most appropriate herbal plants for the removal of contaminants from water and also to develop a water treatment kit at an affordable cost for the society. Moringa Oleifera was chosen for this study, the effectiveness of these herbs in the removal of fluoride from water shows that Moringa Oleifera is economically viable, physically feasible and socially acceptable. Moringa Oleifera seed is an organic material that has proven eff...
Cassava is produced in a large quantity in Nigeria. One of the products emerging from its processing has turned out to be a major staple food in the nation, which is ‘garri’. Due to insufficient and inadequate processing equipment; cassava has been susceptible to wastage and ‘garri’ production has been reduced in scale, thereby resulting in insufficiency and high cost of ’garri’ in the market. In order to ease the production process, a compact mechanized cassava mash/‘...
The aim of the project is to design a renewable energy system that can meet the current and projected electricity demands for the island of Great Cumbrae. This should be achieved by providing a stable electricity output and the meet the calculated total annual base load supply of 11.29 GWh. In addition to providing a stable supply of electricity, the environment and social impacts that arise from the project relating to Great Cumbrae should be minimised as well as coinciding with a techn...
This research is a quantitative study using 4th grade reassessment on one on one technology and its effect on student achievement and motivation.
This is a research work carried out on battery cage system of poultry management. It's all about how to minimize waste from poultry birds and also how to convey waste by employing the help of a belt conveyor
The electricity produced by renewable energy sources (RES) is constantly increasing worldwide thanks to government policies and technological advancements. Photo voltaic cells are actually a fast rising technology as the source of its power is a commodity that is abundant in this part of the hemisphere. Uncertainty also dominates in the area of the conditions at which the photovoltaic cells are operating, their optimal weather conditions and the effect of the conditions on their outpu...
ABSTRACT: This study was carried out in Udi, Udenu and Nsukka Local Government Areas, in Enugu state. The effects of liquid wastes from automobile workshops on some selected soil properties of the study area were investigated. Auger samples were collected at two depths, (surface, 0- 20cm) and (subsurface, 20- 40cm) of automobile wastes contaminated sites and 100m away for uncontaminated sites. Core samples were collected from both soils and surface samples were again collected for planting m...
