  • Reactor Cores At The Three Mile Island
    2,479 words
    In the mid-1950's, nuclear physicists confidently predicted that nuclear energy would usher in a new age for humanity. The cost of energy would be so low it would be almost too cheap to meter. They predicted that by the year 2000 there would be thousands of commercial reactors producing unlimited amounts of power. Like the horse and buggy, oil and coal would become little more than historical curiosities. With such a bright outlook for the future the engineers and scientists started to get carel...
  • First Rule Regarding The Pressure Water
    2,294 words
    Scuba diving is a sport in which you can lose yourself to the beauty of the underwater world and escape gravity for a short time. You can wander among kelp forests or swim with sleek noble sharks. You can find a fortune in Spanish ducats or lose yourself in the beauty of the underwater realm. Some may say though that diving is an extreme sport and that it is too risky for anyone, it's just for the wild hooligans. Scuba Diving is a safe and enjoyable hobby despite the small risk involved. Haven't...
  • Water Vapor Around The Plant
    1,199 words
    Water is essential to plants in many ways. It first provides the major substance for living, to keep cells from shriveling up and dying. The second major function is to keep the plants rigidity. As plant cells become turgid, full of water, the cells expand, filling the extent of their cell walls, which are kept taught with turgor pressure. If the cells lose water, two problems occur. First, the cells dehydrate, causing the organism to die. Second, turgor pressure is lost as cells become flaccid,...
  • Pressurized Water Reactors And The Graphite
    1,356 words
    Nuclear Power Producing energy from a nuclear power plant is very complicated. The process of nuclear energy involves the fission of atoms, the release of energy from fission as heat, and the transfer of heat to electricity in power plants. The process of splitting the atom is called nuclear fission. Fission can take place in many different kinds of atoms. This explanation uses Uranium - 235, the atom most commonly used in nuclear reactors. The Uranium atom has many protons, thus making it unsta...
  • Weren't For Jacques Cousteau The World
    1,499 words
    Jacques Yves Cousteau was born on June 11th 1910 in Saint-Andre-de-Dubzac France. His father was a legal advisor and was fascinated with people like Thomas Edison and his inventions like the light bulb. His mother was a housewife with rich parents. They both had large expectations for their newborn son. Jacques grew up in Andre-de-Dubzac and had many friends. He loved machines and the water in his youth, two things which would be very important in his later years. At the age of 11 he built a bat...
  • Fission Process A Byproduct Of Nuclear Power
    784 words
    The process used was to gather information from books, the Internet, and interviewing my father who works at a nuclear power plant. There are many forms of energy. Coal, gas, oil, and nuclear power are the most common forms of energy used in the United States. Three of these energies are limited: coal, gas, and oil. Nuclear power is unlike the other three because it uses the fission process instead of combustion. This form of power is unlimited. It produces heat energy like the others, but does ...
  • Air Pressure
    951 words
    Pressure Pressure, is the ratio of a force acting on a surface, to the area of the surface; it is thus distinct from the total force acting on a surface. Units of pressure are force units divided by area units. Examples of these are pounds per square inch, dynes per square centimeter, or newtons (N) per square meter (Pressure n. pay). Pressure has many influences and effects on objects. When the pressure rises, it affects the melting point and the boiling point of a substance. This causes the ra...
  • El Nino And La Nina
    650 words
    As the easterly trade winds decrease, the western Pacific's warm water flows toward the Americas. This giant mass of warm water flows over the colder water of the eastern Pacific. As this occurs, we get what is called El Nino, or the child. Its name ("the child") is derived from its arrival during the Christmas season. Typical weather patterns of El Nino include an increase in surface temperatures as well as an increase in cloud cover over the equator. Also, for unknown reasons, a large high pre...
  • Steam Distillation Of An Essential Oil
    492 words
    Steam Distillation Purpose: To use steam distillation to purify heat sensitive, natural products, like essential oils. Procedure Please refer to: Williamson, Macro scale &Microscale Organic Experiments 4th Ed., pigs. 98-109 Results Table 1.1: Steam distillation Drop # (every third drop) Temperature (oC) Addition of 0.5 mL water 1 100.3 Water added 2 100.5 3 100.5 Water added 4 100.6 Water added 5 100.6 6 100.6 Water added 7 100.6 8 100.6 Water added 9 100.3 10 100.6 Observations: The residue was...
  • Buoyancy And Many Other Forces
    437 words
    Scuba diving is an activity enjoyed by people all over the world. Scientists use it to study underwater life, police use it to train in case of emergencies, and many others do it just for fun. What many people don't know, though, is that scuba diving would be impossible without physics. Pressure, buoyancy, and force are big parts of diving. Pressure, the weight pushing on something, is a vital part of scuba diving. As a diver sinks deeper into the water, the pressure pushing on the person's lung...
  • Reactor Core Water
    348 words
    An electrical power plant has a nuclear reactor to produce electricity. A nuclear reactor produces heat through nuclear fission in which atomic muc lei break apart releasing large amounts of energy. In the core of the reactor, a self-sustaining nuclear reaction takes place. The power level of an operating reactor is monitored by a variety of thermal, flow, and nuclear instruments. Power output is controlled by inserting or removing from the core a group of neutron-absorbing control rods. The pos...
  • Water System
    464 words
    The Three Mile Island Disaster - An Organizational Communication Study The accident at the Three Mile Island Unit 2 nuclear power plant near Middleton, Pennsylvania, on March 28, 1979, was the most serious in U.S. commercial nuclear power plant operating history. Even though it led to no deaths or injuries to plant workers or members of the near by community, it did bring about sweeping changes involving emergency response planning, reactor operator training, human factors engineering, radiation...
  • Water Nears The Boiling Point
    363 words
    I went online and found out a lot of information about boiling water. If you cover the tin and allow the water and air to cool down, the air will cool and contract, lowering the pressure in the tin. If it lowers enough, the partial vacuum will collapse the walls of the can! The boiling point definitely reduces with air pressure. There is a famous demonstration where boiling water or coffee is drunk, the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definitio...
  • Landslide Instability And Toe Sheet
    796 words
    The position of thrust sheets around the margins of landslide toe blocks, and their morphology and direction of thrusting, suggests that they were formed as a result of toe block pressing and movement in the surrounding sand. Toe-thrust sheets therefore can be considered as the morphological expression of ongoing instability at the landslide toe. The upthrust nature of these sheets at WestRunton suggests that rotation of toe blocks, generating forward movement of the surrounding loose beach sand...
  • Nitrogen At High Pressure And Deep Water
    500 words
    Human vs. Cetacean Divers Following a deep dive in water, humans can experience severe pains upon returning to the surface too quickly, and the resulting body injury may cause unconsciousness and death. Aches are so severe in some cases, commonly in the joints, that divers bend over in agony. Hence, the name, the bends. However, the more common name for this condition is decompression sickness, meaning that the sickness results from decreasing pressure. Divers experience decreasing pressure upon...
  • Pressure In The Water Between The Ships
    1,172 words
    Bernoulli an Thoughts Daniel BernoulliBernoullian Thoughts Essay, Research Paper Daniel Bernoulli was born into a family of mathematicians on February 8, 1700. He was the only person in his family to make an impressive mark on physics. Bernoulli became a Swiss physicist and mathematician who made enormous contributions to the world of physics. He uncovered many significant phenomena in hydrodynamics, and in 1738, published his most famous work, Hydrodynamica, which was a study of equilibrium, pr...
