• Cooling The Cycle Of Life
    577 words
    Tori Amos is an unabashedly truthful songwriter and singer who builds her lyrics on personal experiences, uncertainties concerning religion and faith, and an undying desire to get in touch with her inner self. Amos's ong "Cooling" is a biography of one woman's life from childhood to death, and ultimately the heroic journey for purity. The first stanza of "Cooling" begins with Amos referring to the death of Speed Racer, a cartoon character. This image is essential in creating a childlike innocenc...
  • Fog Types Lower Layered Clouds

    1. There are five types of fog to be found. There is radiation fog which is the cooling of air to dew point by longwave radiation loss and is considered to be a diabatic process (involving the addition of, or removal of heat). This fog develops when the loss of longwave radiation during the night causes cooling to the dew point. This is most likely to occur on cloudless nights. Another type of fog is advection fog that is the cooling of air to dew point as it passes over cool surfaces. This fog...
  • Nuclear Reactors Fuel Rods
    610 words
    Nuclear Reactors Using a nuclear reactor is an efficient way to produce large amounts of electricity. Nuclear reactors are used to provide power to a neighboring town or city. In a nuclear reactor, water is heated using nuclear energy to the point that it boils and the steam collects around a collection of spinning blades, called a steam turbine. The pressure from the steam turns these blades, which are connected to a dynamo, or generator. The generator is activated and produces electricity, whi...
  • Nuclear Power Fuel Waste High
    1,440 words
    Nuclear Power Most of the world's electricity is generated by either thermal or hydroelectric power plants. Thermal power plants use fuel to boil water which makes steam. The steam turns turbines that generate electricity. Hydroelectric power plants use the great force of rushing water from a dam or a waterfall to turn the turbines. The majority of thermal power plants burn fossil fuels because thermal power plants are cheaper to maintain and have to meet less of the governments requirements com...
  • Solar Energy An Alternative Energy
    294 words
    Solar Energy: An Alternative Energy Imagine a perfect source of energy. One with which no pollution what-so-ever is associated with. No poisonous gasses or destruction of rain forests. This abundant source of energy comes from the sun. Solar energy is the visible energy produced in the sun as a result of a constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared. ...

    The July 2000 issue of Mechanical Engineering explains a new and innovative design for a heat sink, a device used to dissipate heat energy away from a body. Engineers at NEC Computers Inc. of Boxborough, Mass. came up with the design while trying to engineer a heat sink that would protect a computer processor running at high speeds. The new heat sink has the pins, surfaces extended from the main body that are used to increase the rate of heat transfer by increasing surface area, arranged in four...
  • Bleed Air System Cabin Aircraft

    Conan Poi tra The SA 227 family of aircraft are low wing monoplanes, built by Fairchild Aircraft Corporation. These aircraft include the Merlin IIC, Merlin IVC, and the Metro III. These three aircraft are powered by two turboprop engines equipped with constant speed, full feathering, four blade, reversible propellers made by Do wty-Roto l, or McCauley propellers. The cabin is pressurized, heated and cooled by bleed air which is ducted through valves, heat exchangers, and refrigeration unit. The ...
  • Pump Rebuilding Suction And Discharge
    389 words
    Today most of our electric power is produced by Nuclear Power Plants. Nuclear reactors must be constantly cooled in order to maintain a level of safety. There are two types of pumps used for cooling the reactor, the centrifical pump, and the circulating pump. The cooling water pump is a critical part in a nuclear plant and must be rebuilt continuously to avoid a reactor melt down. Here are some simple instructions that, if followed, will make your rebuild job safe, reliable and quick. First, loc...
  • Principles Of Heat Treating Of Steels
    1,567 words
    Principles of Heat Treating of Steels A steel is usually defined as an alloy of iron and carbon with the content between a few hundreds of a percent up to about 2 wt%. Other alloying elements can amount in total to about 5 wt% in low-alloy steels and higher in more highly alloyed steels such as tool steels and stainless steels. Steels can exhibit a wide variety of properties depending on composition as well as the phases and microconstituent present, which in turn depend on the heat treatment. T...

  • Refrigeration Cooling Process
    441 words
    What is Refrigeration? In general, refrigeration is defined as any process of "HEAT REMOVAL." More specifically, refrigeration is defined as the branch of science that deals with the process of reducing and maintaining the temperature of a space or material below the temperature of the surroundings. To accomplish this, heat must be removed from the body being refrigerated and transferred to another body whose temperature is below that of the refrigerated body. Since heat will always move from a ...
