  2. Cooling tower - Wikipedia

    en.wikipedia.org/wiki/Cooling_tower

    The interactions of the air and water flow allow a partial equalization of temperature, and evaporation of water. The air, now saturated with water vapor, is discharged from the top of the cooling tower. A "collection basin" or "cold water basin" is used to collect and contain the cooled water after its interaction with the air flow.

  3. History of fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/History_of_fluid_mechanics

    The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...

  4. Origin of water on Earth - Wikipedia

    en.wikipedia.org/wiki/Origin_of_water_on_Earth

    The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System in having oceans of liquid water on its surface. [ 2] Liquid water, which is necessary for all known forms of life, continues to exist on the surface of ...

  5. Primordial soup - Wikipedia

    en.wikipedia.org/wiki/Primordial_soup

    Primordial soup, also known as prebiotic soup, is the hypothetical set of conditions present on the Earth around 3.7 to 4.0 billion years ago. It is an aspect of the heterotrophic theory (also known as the Oparin–Haldane hypothesis) concerning the origin of life, first proposed by Alexander Oparin in 1924, and J. B. S. Haldane in 1929. [ 1 ...

  6. Decoupage - Wikipedia

    en.wikipedia.org/wiki/Decoupage

    Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...

  7. Evolutionary history of plants - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_history_of_plants

    As CO 2 was withdrawn from the atmosphere by plants, more water was lost in its capture, and more elegant water acquisition and transport mechanisms evolved. [44] Plants growing upwards into the air needed a system for transporting water from the soil to all the different parts of the above-soil plant, especially to photosynthesising parts.

  8. Underwater diving - Wikipedia

    en.wikipedia.org/wiki/Underwater_diving

    Underwater diving. Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have physiological effects ...

  9. Ocean thermal energy conversion - Wikipedia

    en.wikipedia.org/wiki/Ocean_thermal_energy...

    Ocean thermal energy conversion ( OTEC) is a renewable energy technology that harnesses the temperature difference between the warm surface waters of the ocean and the cold depths to run a heat engine to produce electricity. It is a unique form of clean energy generation that has the potential to provide a consistent and sustainable source of ...
