  2. Compressibility factor - Wikipedia

    en.wikipedia.org/wiki/Compressibility_factor

    Once two of the three reduced properties are found, the compressibility chart can be used. In a compressibility chart, reduced pressure is on the x-axis and Z is on the y-axis. When given the reduced pressure and temperature, find the given pressure on the x-axis. From there, move up on the chart until the given reduced temperature is found.

  3. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    The Oceanic carbon cycle is a central process to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.

  5. Oxygen cycle - Wikipedia

    en.wikipedia.org/wiki/Oxygen_cycle

    The rate of organic carbon burial was derived from estimated fluxes of volcanic and hydrothermal carbon. [4] [5] Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these ...

  6. Compressibility - Wikipedia

    en.wikipedia.org/wiki/Compressibility

    The compressibility factor is defined as = where p is the pressure of the gas, T is its temperature, and is its molar volume, all measured independently of one another. In the case of an ideal gas, the compressibility factor Z is equal to unity, and the familiar ideal gas law is recovered:

  7. Ocean stratification - Wikipedia

    en.wikipedia.org/wiki/Ocean_stratification

    A decline in dissolved oxygen, and hence in the oxygen supply to the ocean interior, is a likely effect of the increase in stratification in the upper ocean. [15] Since oxygen plays a direct and important role in the cycles of carbon, nitrogen and many other elements such as phosphorus, iron and magnesium, de-oxygenation will have large ...

  8. Aquatic respiration - Wikipedia

    en.wikipedia.org/wiki/Aquatic_respiration

    These filaments have many functions and are involved in ion and water transfer as well as oxygen, carbon dioxide, acid and ammonia exchange. [4] Each filament contains a capillary network that provides a large surface area for the exchange of gases and ions. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it ...

  9. Non ideal compressible fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Non_ideal_compressible...

    The compressibility factor is a dimensionless quantity which is equal to 1 for ideal gases and deviates from unity for increasing levels of non-ideality. [ 9 ] Several non-ideal models exist, from the simplest cubic equations of state (such as the Van der Waals [ 4 ] [ 10 ] and the Peng-Robinson [ 11 ] models) up to complex multi-parameter ones ...
