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.

Global warming is the gradual rise in the temperature of the earth’s surface, oceans and atmosphere. Global warming is caused by the Greenhouse Effect, which humans are responsible for. Due to the burning of fossil fuels, there has been an increase of carbon dioxide and greenhouse gasses in the earth’s atmosphere and because of this the suns heat becomes trapped and cannot escape through the earth’s atmosphere which in turn causes our planet to heat up. Increased rainfall, droughts and floods…

Berylliosis is an occupational lung disease. It occurs in people who work with beryllium (beryllium is an element of the periodic table, is used to make things like airplanes, x-rays or nuclear reactors. It is found in coal in the ground.) And have the same allergic sensitivity. The workers are the most affected of all. It is the staff working in the nuclear sector. This cause is because the people inhale the air so the beryllium goes into the longs and they are affected. There are Pros and…

InSinkErator Badger 5 InSinkErator Badger 5 features - The Badger 5 is a simple, no-frills garbage disposal. It’s constructed with galvanized steel parts (they won’t rust). The ½ horsepower motor provides more than enough power to liquify almost any kitchen waste. The Badger 5 is a continuous-feed type of disposal. Simply put, turn on the water in the kitchen sink. Then push your fruit peels, coffee grounds, spoiled vegetables, even small chicken bones down the disposal. The disposal…

solid, liquid or gas and the oxidizer, the source of oxygen can also be a solid liquid or gas. A new chemical substance is created from the fuel and source of oxygen. These new chemical substances are referred to as exhaust. For combustion to occur, a fuel, oxygen and heat are required. In an alkane, the more carbon atoms that are present, the more heat that is produced because of combustion. Examples of Alkane Fuels: • Methane – main alkane present in natural gas (e.g. North Sea gas) •…

I. Introduction Over the years, it has been observed that the temperature of the earth has been getting warmer and warmer. Many would simply shrug this off as fluctuations in the weather, but this has been proven to not be the case. This increase in temperature has been determined to be caused by excess amounts of carbon dioxide in the atmosphere. Carbon dioxide traps sunlight in the atmosphere which makes the earth warmer. The excess amount of carbon dioxide released into the atmosphere is a…

happened after a fracking well had been in operation nearby for a period of time. Mr. Ely of Pennsylvania signed a leasing contract with a major oil and gas company and after speaking with the salesman for the company “felt certain it required the company to leave the property as good as new.” When the terms of the lease had come to an end, Cabot Oil and Gas told the Ely’s that instead of removing the waste from their drilling efforts, they would “cover it with dirt and seed the area with…

these greenhouse gases has increased dramatically in the atmosphere, leading to global warming. According to the the EPA (The US Environmental Protection Agency), the largest sources of greenhouse gas emission in the United States of America are, electricity, making up around 30% of all greenhouse gas-emitting…

Causes and Impact of Global Warming Climate changes have a long term impact to patterns of temperature, rain, snow, and wind. The shift in temperature creates global warming which is an average increase in temperature near the earth’s surface and the lowest layer of the atmosphere. The climate change affect people and the environment in many different ways. The idea on remaining vital with climate changes is to identify the social problem of environmental inequalities for the adaptations to…

With the growing population in the past years comes an increase in urbanization and industrialization, thus increasing the number of buildings in urban areas and consequently this means an overall rise in energy usage by the people. The increase in population and amount of people moving into urban areas is occurring at an alarming rate, but this doesn’t come as a surprise. Ever since 1950 this has been occurring. From 1950 to 1986 there was an increase from 600 million to 2 billion people…
