  2. Gas blending for scuba diving - Wikipedia

    en.wikipedia.org/wiki/Gas_blending_for_scuba_diving

    Regulators supplying a controlled flow of oxygen and helium to a continuous blending system for trimix or nitrox. Gas blending for scuba diving (or gas mixing) is the filling of diving cylinders with non- air breathing gases such as nitrox, trimix and heliox. Use of these gases is generally intended to improve overall safety of the planned dive ...

  3. Common ethanol fuel mixtures - Wikipedia

    en.wikipedia.org/wiki/Common_ethanol_fuel_mixtures

    Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...

  4. Gas blending - Wikipedia

    en.wikipedia.org/wiki/Gas_blending

    Gas blending. Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is specified and controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases. Gas mixtures are usually specified in terms of molar gas fraction ...

  5. Amagat's law - Wikipedia

    en.wikipedia.org/wiki/Amagat's_law

    Amagat's law assumes that the volumes of the component gases (again at the same temperature and pressure) are additive; the interactions of the different gases are the same as the average interactions of the components. The interactions can be interpreted in terms of a second virial coefficient B ( T) for the mixture.

  6. Nitrox - Wikipedia

    en.wikipedia.org/wiki/Nitrox

    Nitrox. One type of nitrox cylinder identification label. Nitrox refers to any gas mixture composed (excepting trace gases) of nitrogen and oxygen. This includes atmospheric air, which is approximately 78% nitrogen, 21% oxygen, and 1% other gases, primarily argon. [1] [2] [3] In the usual application, underwater diving, nitrox is normally ...

  7. Breathing gas - Wikipedia

    en.wikipedia.org/wiki/Breathing_gas

    A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...

  8. Trimix (breathing gas) - Wikipedia

    en.wikipedia.org/wiki/Trimix_(breathing_gas)

    Trimix scuba cylinder label IMCA Trimix cylinder shoulder colour code alternative IMCA Trimix cylinder shoulder colour code. Trimix is a breathing gas consisting of oxygen, helium and nitrogen and is used in deep commercial diving, during the deep phase of dives carried out using technical diving techniques, [1] [2] and in advanced recreational diving.
