Heating

CONVERSION OF SOLAR ENERGY FOR USE Producing solar power is just as simple as using the sunlight that heats the surface of the earth. Now, more than ever, it has become an important alternate energy source. It can be used in two different ways, as a heating source and as an energy source. It can generate heat, lighting and electricity. Understanding how this important energy source is produced is just the beginning. Harnessing the Sun's…

Heat Up The World! Recently, the biggest natural environment problem is Global Warming. Scientists say that the earth is heating up and this is causing waters to rise and ice caps are melting. What’s the big deal? Don’t we want bigger waves to surf on? Since, Global Warming is a natural process: greenhouse gases are trapped in the atmosphere, shouldn’t we roll with it? This is what nature is deciding to do and we can’t go against it. It’s better that we agree and go along with what nature is…

normal cigarette. E-cigarette has a higher price than normal cigarette. E-cigarette has many necessary composition before it can use. For example, it necessary to use an e-liquid to be a smoke ingredient and some e-cigarette have to replace a coil for heating an e-liquid to be a vapor for many times per week. While normal cigarette is very simple to use. It just need a lighter or anything that can create a fire to burn a tobacco in cigarette and then all you have to do is just smoking it. This…

Washington citizens were surprised by cherry blossoms and snowfall, last November and December. Climate change has contributed to those kinds of unusual phenomena. Weather is the day-to-day conditions of a particular place, but “climate is the average weather, including seasonal extremes and variations, either locally, regionally or across the globe” (Union of Concerned Scientists 2011, p185). Why Toronto is still cold and negative degree end of April?. Burning fossil fuel, deforestation and…

The purpose of this experiment was to evaluate the stoichiometric relationship between the testing agents and to identify the products formed. The relationship was found by completing three acid and base neutralization reactions using phosphoric acid, which is a triprotic acid, with different volumes of sodium hydroxide. Introduction When looking at the coefficient of balanced equations, stoichiometry is seen. Coefficients represent the number of moles, equivalent to the mass of an atom, of…

“flashing”. Steam conducted by flashing is diverted to freshwater by condensation on tubular heat exchangers which run through each stage. Then the tubes are cooled down using incoming feed water on the way to the brine heater which has the effect of heating the feed water so that the thermal energy amount required to increase its temperature in the brine heater is decreased. Distillate streaming from stage to stage is brought out as product water from the last stage. Then it may be treated…

investigate the overall heat transfer ( Uₒ ) for the external heat exchanger at two different water circulation rates by using two methods “ Heating Liquids in Tank Storage ” and “ Corning Heat Exchanger “ . Briefly, the measurements were done by changing the volume flow rate between 40 lbm/min and 70 lbm/min for the first part of the experiment which was “Heating Liquids in Tank Storage”. However, for the second method, the measurements were taken by changing the flow rate for the second…

The greenhouse effect is a system in which certain gases in the Earth’s atmosphere trap infrared radiation emitted from the Earth and re-radiate it in all directions. This causes additional heating of the Earth. As the radiation from the Sun is absorbed by the Earth’s surface, the energy is converted to thermal energy. Then, the Earth radiates lower-energy infrared radiation back out to the atmosphere and space. The Earth’s atmosphere and clouds absorb this infrared energy and radiation directed…

sample was then folded within the filter paper and stored for 2 days inside the crucible until the next lab day. The following lab day, each crucible is heated on a Bunsen burner on a ring stand. The flame was moved around to avoid excessive initial heating and that the crucible is heated evenly. Once the filter paper was charred, the temperature of the flame was increased. When all of the black carbon residue has been removed, the temperature of the flame was maximized so that the tip of…

DESCRIPTION The olecranon is the pointy bone at the tip of the elbow. The Bursae are thin, slippery sacs located throughout the body that act as cushions between bones and soft tissues. They contain a small amount of lubricating fluid that allows the skin to move freely over the underlying bone. However, the bursa can become irritated or inflamed and fill with extra fluid. When this happens, a painful swelling develops at the back of the elbow. This swelling is olecranon bursitis. CAUSE •…
