  2. MODFLOW - Wikipedia

    en.wikipedia.org/wiki/MODFLOW

    MODFLOW-OWHM [11] (version 1.00.12, October 1, 2016), The One-Water Hydrologic Flow Model (MODFLOW-OWHM, MF-OWHM or One-Water [12]), developed cooperatively between the USGS and the U.S. Bureau of Reclamation, is a fusion of multiple versions of MODFLOW-2005 (NWT, LGR, FMP, SWR, SWI) into ONE version, contains upgrades and new features and ...

  3. Ferric EDTA - Wikipedia

    en.wikipedia.org/wiki/Ferric_edta

    The [Fe(EDTA)(H 2 O)] − anion has been crystallized with many cations, e.g., the trihydrate Na[Fe(EDTA)(H 2 O)]. 2H 2 O. [3] The salts as well as the solutions are yellow-brown. Provided the nutrient solution in which the [Fe(EDTA)(H 2 O)] − complex will be used has a pH of at least 5.5, all the uncomplexed iron, as a result of incomplete ...

  4. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance. The ...

  5. Iron(III) acetate - Wikipedia

    en.wikipedia.org/wiki/Iron(III)_acetate

    Ferric acetate is the iron compound with the formula Fe 3 O(O 2 CCH 3) 6 (H 2 O) 3]O 2 CCH 3. This red brown solid is the acetate salt of the coordination complex [Fe 3 O(OAc) 6 (H 2 O) 3] + (OAc − is CH 3 CO 2 −). Commonly, the salt is known as "basic iron acetate". [2] The formation of the red-brown complex was once used as a test for ...

  6. Mass transfer coefficient - Wikipedia

    en.wikipedia.org/wiki/Mass_transfer_coefficient

    Mass transfer coefficients can be estimated from many different theoretical equations, correlations, and analogies that are functions of material properties, intensive properties and flow regime (laminar or turbulent flow). Selection of the most applicable model is dependent on the materials and the system, or environment, being studied.

  7. Maxwell–Stefan diffusion - Wikipedia

    en.wikipedia.org/wiki/Maxwell–Stefan_diffusion

    For complex systems, such as electrolytic solutions, and other drivers, such as a pressure gradient, the equation must be expanded to include additional terms for interactions. A major disadvantage of the Maxwell–Stefan theory is that the diffusion coefficients , with the exception of the diffusion of dilute gases, do not correspond to the ...

  8. Potassium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    Potassium hexacyanidoferrate(II) is the inorganic compound with formula K 4 [Fe(CN) 6]·3H 2 O. It is the potassium salt of the coordination complex [Fe(CN) 6 ] 4− . This salt forms lemon-yellow monoclinic crystals .

  9. Amount of substance - Wikipedia

    en.wikipedia.org/wiki/Amount_of_substance

    Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...
