Engines-petrol and diesel INTRODUCTION:- Petrol Engine: It is an internal combustion engine (known as gasoline engine in North America). It consists of a spark ignition and design to run on petrol and similar volatile fuels. The fuel mixing was done in carburettor in earlier days but now it is done using fuel injection. Petrol engines runs at higher speed than diesel engine, this is due to the small size of piston. Petrol engine has many applications like: 1) Motorcars 2) Motorcycles…

At the turn of the twentieth century, a Native American group, the Osage were forced off of their lands and forced to sell. The group moved to what would soon become Oklahoma and bought the land from the federal government for all it was worth, especially what was bellow it. When oil was discovered under the land, the Osage leased their lands to the highest bidder and became some of the richest citizens in America almost overnight. Due to the prejudice towards Native Americans, the government…

RESULTS AND DISCUSSION Air pressure in the blow tube Figure 3 represents air pressure in the blow tube for 4 bar and 6 bar reservoir pressures. Considering only the 4 bar reservoir pressure case, peak pressure observed is 379538.2 Pa, which is 274.5% more than atmospheric pressure. And peak pressure observed is not equal to 4 bar, which can be attributed to the frictional losses in the blow tube and in the pipe connecting blow tube and air reservoir. Fig. 3 Variation of air pressure with…

starting with holding workshops and lecture series on university campuses. This will require building relationships and networking with universities such as the American University of Iraq, University of Tehran in Iran and the King Fahd University of Petroleum & Minerals in Saudi…

Fracking, also known as hydraulic fracturing, is a type of drilling that uses water, sand and chemicals, shot at high pressure, to release energy resources trapped inside rocks. This recently new technology for drilling allows areas that were previously inaccessible for drilling, like very concentrated rocky areas, to now be opened up through fracking to obtain natural gases and oil. The water solution used with this drilling technique produces almost the same amount of “sludge” as an after…

Oil is a fossil fuel used in everyday lives, yet this abundant resource is not infinite so requires new pockets to be continually found. Worldwide concerns have sparked many controversies over whether oil has been reached its maximum extraction known as ‘peak oil’. There is also a worldwide concern towards on what will happen when in Marion King Hubbert graph reaches the declining period. In the social aspect it could lead to even more political instability between countries and cause conflicts…

Fracking: A Small Benefit with Innumerable Hazards Fracking, also known as hydraulic fracturing, is a process used to obtain natural gas from shale rock formations. This type of drilling is used with another type called “horizontal drilling” (The Pennsylvania Guide to Hydraulic Fracturing, or "Fracking). A common question that arises is “Why is fracking being done?” The answer is simple and a quote by Jeremy Grantham perfectly explains this question. The quote is “The world is using up its…

Across the planet, the human race has begun to take notice of a rapidly changing climate. Of particular concern is the unnaturalness of such a global climate change, pointing to the fact that it is largely mankind’s doing, or rather, undoing. In addition to climate change, environmental problems such as water and air pollution, species extinction, and deforestation are rampant, indicating the all-encompassing degradation of industrial activities on the natural world. However, hydraulic…
