Global warming and climate change: Threats and impacts Global warming and climate change are “the talk of the town” in this century, with its unhealthy effects already being brought to lime light by its annihilate power of damaging the society by floods in one part of the country and droughts on another. Before embarking impacts of global warming and climate change, we should know what green house effect mean. GREEN HOUSE EFFECT Green House effect is the phenomenon in which the earth's…

When studing liquid fuel combustion in gas turbine combustor, complicated principals including reactive flow, spraying, turbulent flow, multiphase flow, convective and radiative heat transfer and their interactions should be considered. In recent 40 years combustion chambers have continuously improved structurally. Present combustion chambers are generally devided to three main groups: Can type, Can Annular type, and Annular type chambers. Combustion chambers consist of components such as…

Minerals and their derived products are the foundation of many important industries. Mines and quarries can be found in almost every country all around the world. Mining industry products provide most of the needed energy, from electricity in homes and industries, to fuel in cars, machinery and tools Resources obtained from mines are also used as inputs for raw materials, consumer goods as well as for almost all services and processes provided by other industries, such as: manufacturing…

deeper they are wrapped around the Earth like a blanket by the chemical carbon dioxide. Carbon dioxide is put into the air by the burning of fossil fuels such as coal and natural gas. According to ucsusa.org, “Global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars. Carbon dioxide spreads around the planet like a blanket, and is one of the main gases responsible for the…

Introduction Acid rain is a rain that contains a high concentration of pollutants, chiefly sulfur dioxide and nitrogen oxide, released into the atmosphere by the burning of fossil fuels such as coal or oil .It can have harmful effects on plants, aquatic animals and infrastructure, when the sulfur dioxide and nitrogen oxide, react with the water . The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.…

Introduction: Business was started by Shell in Nigeria in 1937 as Shell darcy and was given a license of exploration .Olioberi was the first commercial oil field discovered in the Niger Delta. Prior to discovery of oil, Nigeria depended on agricultural exports to other countries. The largest fossil fuel company in Nigeria is Shell Petroleum Development Company, which operates over 6000 kms. The villages’ individuals surrounding facilities of oil production occasionally drill holes into pipelines…

Climate Change is the main issue not only one nation but also global impressing and concerning. The global average temperature increased about 0.74 oC during 100 years from 1906 to 2005 and it will be grown 2 oC more in the next 100 years if human activities remain producing greenhouse gases as the same now. (IPCC, 2007). Climate change will bring about prolong drought, frequent and intended flooding, and other natural calamities. Then the impacts from these climatic disasters will be differed…

experimental work are shown below in table. In this investigation experimental and computational analysis of fin array is done. For Computational analysis they used Ansys Fluent-12 software. Table 1: Different parameters of fin array used Sr. No. L (mm) H (mm) S (mm) No. Of Fins Depth of Notch 1 127 38 8 7 Without Notch 2 127 38 8 7 40% 3 150 75 8 7 40% 4 175 85 8 7 40% It is concluded that the in notch fin array the heat transfer coefficient is more than without notch fin…

1. What are Seismic Imaging Technology and Chevron use of the technology? Seismic Imaging is a tool/technique to find the availability of crude oils and natural gas underground. It is also known as reflection Seismology as it is a process of inspection geophysics to evaluate the properties of Earth’s subsurface by using the principles of seismology from the reflected seismic waves. Sound waves are recorded by Seismologists using an ultrasensitive device called geophone as they echo under the…

Global Warming The climate system of Earth responds to changes in external factors that are able to push the climate towards warming or cooling. These factors include changes in atmosphere composition (concentration of greenhouse gases), volcanic eruptions, and solar activity changes. All of these factors combined create current tendency of climate change that is described by the term “global warming”. Global warming is the continuous rise in average temperature of Earth's climate system.…
