ABSTRACT Surface studies done in Menengai field have indicated a huge geothermal potential and has led to the drilling of several wells. However, some of these wells have not produced as earlier projected and there are questions as to whether this field has enough permeability. The purpose of this study was to employ gravity method to understand density variations in the Menengai field by developing structural models and establishing whether there is enough permeability. Raw data received fr...
ABSTRACT Good maintenance planning and proper resources scheduling in corn milling industry are of fundamental importance for safe and efficient operation of corn milling plants. This leads to production optimization due to reduced cost of operation. The interactions of aspects of plant safety and reliability with issues related to economic performance, such as production revenues, repair and maintenance costs, renders the problem of managing maintenance and repair activities highly complica...
ABSTRACT Generator load is the key focus of a power plant which is significantly affected by its generating equipment which can be determined by both maintenance and the running parameters. The parameters of interest for this study were turbine inlet pressure, steam flow rate, steam chest pressure (Bowl pressure) and Generator Loading. The operation of Olkaria II power plant was started in the year 2002, with Unit I turbine taking steam at a flow rate of 62.5 Kg/Sec (225 ton/hr). After opera...
Steel plays a very key role in the transformation of an economy, as it is the key driver in any industrial revolution majorly being used in transport, building and construction, power generation and machinery. It is in this regard that the study of iron and steel in Kenya is important. This study sought to determine the viability of setting up an iron and steel processing plant in Kenya, develop a process design for such a plant and determine the plant's economic feasibility. This research em...
ABSTRACT Spinning mills in Kenya are operated by eight integrated textile industries to produce cotton yarns for internal use by their knitting and weaving departments and for sale to the local market. Fabric requirement estimated at 225 million square meters cannot be supplied by local domestic production and the gap is met through importation of fabrics and finished garments. Spinning mills play a very significant role in backward integration of the textile value chain by converting fibres...
Abstract Bioremediation has been proven to be the most effective method of cleaning up oil contaminated soils through the application of nutrients and microorganism to contaminated soils. Hence, this research was aimed at investigating the effects of particle sizes on bioremediation of crude oil polluted sandy soils. Six different soil samples were sieved using the B.S sieve sizes. The sieve sizes were classified into X and Y such that X is fine to coarse sand while Y is very fine to coarse ...
Productivity of a system is one of the key factors that affects overall competitiveness of an organisation. Productivity is the measure of the effective use of resources which is expressed as the ratio of output to inputs. Therefore productivity is the relationship between result and the time it takes to accomplish them and it is used to examine efficiency and effectiveness of any activity that is conducted in an economy,business or an individual hence it refers to the measure of the efficie...
ABSTRACT In this thesis, the objective is to determine the steady state operating condition of thirteen bus Ogui- Enugu Radial power distribution network. The steady-state was determined by finding out, for a given set of loading conditions, the flow of active and reactive powers throughout the network, the voltage magnitudes and phase angles at all buses of the network. This was achieved using Newton- Raphson power flow algorithm written in MATLAB environment. A critical analysis of the net...
ABSTRACT This project involves research on loss reduction in a distribution system. The Enugu distribution system is the case study. The type of losses, the causes of losses and methods of loss reduction in distribution system were presented. A method based on a heuristic technique for reactive loss reduction in distribution system is chosen for this work because it provides realistic sizes and locations for shunt capacitors on primary feeder at a low computational burden. The Gauss-siedel m...
Abstract Due to intense global competition and increasing demands from stakeholders, companies are striving to improve and optimize their productivity in order to stay competitive. The performance and competitiveness of manufacturing companies is dependent on the reliability and availability of their production facilities. Therefore, it is the objective of the maintenance department to maximize the machine availability. The use of effective maintenance policies is one of the methods that hav...
ABSTRACT A research was carried out at the Ngongongeri Farm Kenya to determine effects of tillage depth and speed on drawbar power and performance of disc and mouldboard ploughs so as to develop a mathematical model that would assist farmers, machinery managers and policy makers to properly match implements to tractors and the size of tractors to import based on soil types and conditions. The implements used were a standard 2-bottom mouldboard plough and a 3-bottom disc plough. Tillage depth...
The use of technology in communication has proliferated in the last decade, more so with the advancement of mobile technology which has made information dissemination and reception more instantaneous. With the advancement in mobile communication technology, platforms have come up and have been adopted by many who find them appealing. One of these platforms is WhatsApp, whose adoption rate has enormously grown from its inception in 2009, with the current number of users surpassing 1 billion in...
The purpose of this project was to build a motion detector. The main components used were the Arduino microcontroller and the PIR sensor. The project also used an LED and a Piezo buzzer to indicate when motion was detected. The group sought to demonstrate the workings of each component as well as how they work together to carry out the task. The group also drew up a circuit from which the components were connected. The main objective for the project was to practice the skills learnt over t...
ABSTRACT This research work undertakes the development of water pumping system (with emphasis on Irrigation) that is capable of automatically managing water budgets from a reservoir through a microcontroller subsystem. The water pumping for irrigation system can be used in gardens, farms, urban/rural water supply systems, and in fact, general water management systems for both domestic and industrial applications. The key objective of this research is to develop a user-friendly and efficient ...
ABSTRACT This thesis presents the performance characteristics of a Transfer Field (TF) machine. In this machine, the two component fields revolving in the airgap are of the same pole number and the speed of operation is inversely proportional to the sum of the two pole numbers, that is, half the synchronous speed 𝜔2 of a normal induction motor. There is thus, a close relationship between the self-cascaded induction machine and the TF machine. It is shown that if the reactance of the...
