On April 20, 2010, the exploratory Macondo well experienced an explosion that not only created one of the most catastrophic environmental disasters in U.S. history but killed 11 people (Barstow, Rohde & Saul, 2010). The environmental effects were devastating. It took 87 days ...

Analysis of Incident Investigation Data for Causal Factors

Abstract Accidents may be caused by various conditions: the worker’s physical and psychological condition, safety rules control, overload at work, lack of manual to prevent accidents from happening. If the worker in poor physical condition, tired and incapable of thinking clearly, he should not be allowed to work any further for safety reasons, and those conditions of workers should be defined by the company’s safety control officers before letting him start the job. Giving overtime to workers also needs careful test of workers’ physical condition. Sometimes exploited may not be equipped with safety terms. Working with dangerous ...

Introduction

How materials behave is dependent on various factors, some of which include their mechanical properties. When the material experiences various loading conditions, its behavior reflects its mechanical conditions as well as the effect of the loading conditions. When a material experiences various loading conditions, the material experiences either shear stress, tensile strength, or compressive strength. The tensile properties of a material relate to its ability support any axial loads to which it is subjected without rapturing (Department of Engineering. 2007). When a material is subjected to tensile stress, the deformation that occurs is in the form of elongation or ...

Introduction: All most all metals are unstable when exposed to air. This is because of the tendency of the metal to be converted into its oxidized form on reaction with air. When compared to zinc, iron has a greater tendency to form oxidized form and thus has greater susceptibility to corrosion. The ability of metals to react with air varies and this determines their relative stability. As zinc is much stable when compared to iron, it is used to galvanizing iron pipe, thus preventing contact of iron with air and water that contains dissolved air. Brass is an alloy ...

Introduction

The flow of a given volume of fluid through a pipe requires a given amount of energy. In order for fluid flow to occur, there must be pressure or energy difference. During fluid flow through a pipe, energy is lost. The main causes of this loss are the resistance encountered by the fluid in the process of its movement through the pipe. Viscosity is one of the most common forms of resistance to fluid flow through a pipe (Noltingk, 1985, p. 5). Fluids that have high viscosity tend to exhibit high resistance while flowing through a pipe (Considine and ...

BERNOULLI’S EXPERIMENT

ABSTRACT Two fluid properties, the Bernoulli principle and the Venturi effect, were examined and analyzed in this experiment. A venturi meter was used to measure the fluid flow rate, velocity, and pressure of water (the fluid being examined). The results showed that the fluid pressure decreases as the fluid traveled through a smaller cross sectional area. The minimum fluid pressure (in effect, maximum fluid velocity) was observed in the smallest cross sectional area at position D (diameter 16 mm). The decrease in fluid pressure was compensated by an increase in the fluid velocity. With these two measured phenomena, both ...

Introduction A wind instrument is an instrument that produces sound by manipulating air through varying the wind pressure passing through the air outputs of the device (Berg and Stock, 27). These devices are heavily dependent on pressure as well as the size and shape of the instrument (pg. 28). A good example of a wind instrument is the organ pipe. It is a tool that produces a specific pitch when pressurized air is driven through it. Organ pipes usually exist in sets, where each is confined to produce a specific tune. Normally, it is a keyboard device that is ...

According to EPA (2016), environmental management involves the development of systems aimed at reducing environmental impacts of various activities. In the Brundtland commission report (WCED), sustainable development has been described as development aimed at meeting the current needs of the present generation. However, as the current generation focuses on meeting their own needs, their activities should not compromise the capability of future generations to also meet their own needs. Available evidence suggests that the future generation would have challenges meeting their own needs if the current generation fails to adopt sustainable practices. The sustainable development incorporates the triple line: ...

Quite often, people who smoke tobacco are perceived to be at a higher risk of lung cancer and other conditions associated with the smoking of tobacco than the people who though do not smoke, live with smokers. However, this perception is not necessarily accurate. Individuals who are exposed to the smoke from a burning tobacco have equal or higher chances of developing conditions associated with tobacco-smoking than their counterparts who are active tobacco smokers. The smoke from a burning tobacco can be inhaled by a non-tobacco smoker involuntarily. This kind of smoke is referred to as a secondhand smoke ( ...

Pump Application: Building Water Pump

Pumps are devices used to move fluids from one point to another by creating differences in pressure between the two points. Pumps are powered by a prime mover, which can be either a diesel engine or an electric motor. The pump converts the energy supplied by the prime mover to potential energy by pressurizing the fluid it’s pumping. For example, a diesel pump has an engine that converts chemical energy in the fuel to mechanical energy in the form of torque. The torque from the engine is then picked up and transmitted to the pumping mechanism for fluid ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant. In piping systems, however, there are several water quality factors working singly ...

Question Number One

The realist international relations theory stipulates that a competitive self-interest is the main driving force of world politics. The theory is based on premises that the international political system is anarchic. States are the most important players in world politics and they tend to seek self-interest and survival is the major concern of all states. It has been theorized that “nations dwell in perpetual anarchy for no central authority imposes limits on the pursuit of sovereign interests” (Oye, 1). Anarchy stems from the fact that there is no common or central government in world politics (Axelrod and Keohane, 226). ...
