  2. 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 ...

    1834 – Benoît Paul Émile Clapeyron – Ideal gas law. 1836 – John Frederic Daniell invents a primary cell in which hydrogen is eliminated in the generation of the electricity. 1839 – Christian Friedrich Schönbein publishes the principle of the fuel cell in the "Philosophical Magazine". 1839 – William Robert Grove develops the Grove cell.

  7. Degasser - Wikipedia

    en.wikipedia.org/wiki/Degasser

    For a small amount of entrained gas in a drilling fluid, the degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped [1].In order for it to be released and break out the air and gas such as methane, H 2 S and CO 2 from the mud to the surface, the drilling fluid must pass through a degassing technique, and it can be accomplished by the equipment ...

    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 ...
