  2. Mixed liquor suspended solids - Wikipedia

    en.wikipedia.org/wiki/Mixed_liquor_suspended_solids

    Environmental engineering focuses on the particles suspended in water and the suitable operation of water treatment plants. Therefore, it is important to measure the total mass of suspended solids, which is the MLSS, as well as the mass of organic matter suspended in the activated sludge unit.

  3. Cooking weights and measures - Wikipedia

    en.wikipedia.org/wiki/Cooking_weights_and_measures

    The system can be traced back to the measuring systems of the Hindus [18]: B-9 and the ancient Egyptians, who subdivided the hekat (about 4.8 litres) into parts of 1 ⁄ 2, 1 ⁄ 4, 1 ⁄ 8, 1 ⁄ 16, 1 ⁄ 32, and 1 ⁄ 64 (1 ro, or mouthful, or about 14.5 ml), [19] and the hin similarly down to 1 ⁄ 32 (1 ro) using hieratic notation, [20] as ...

  4. Mass concentration (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_concentration_(chemistry)

    In water solutions containing relatively small quantities of dissolved solute (as in biology), such figures may be "percentivized" by multiplying by 100 a ratio of grams solute per mL solution. The result is given as "mass/volume percentage". Such a convention expresses mass concentration of 1 gram of solute in 100 mL of solution, as "1 m/v %".

  5. Mass fraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_fraction_(chemistry)

    A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because the unit "%" can only be used for dimensionless quantities. Instead, the concentration should simply be given in units of g/mL.

  6. Mixing ratio - Wikipedia

    en.wikipedia.org/wiki/Mixing_Ratio

    In chemistry and physics, the dimensionless mixing ratio is the abundance of one component of a mixture relative to that of all other components. The term can refer either to mole ratio (see concentration ) or mass ratio (see stoichiometry ).

  7. Dilution (equation) - Wikipedia

    en.wikipedia.org/wiki/Dilution_(equation)

    For example, if there are 10 grams of salt (the solute) dissolved in 1 litre of water (the solvent), this solution has a certain salt concentration . If one adds 1 litre of water to this solution, the salt concentration is reduced. The diluted solution still contains 10 grams of salt (0.171 moles of NaCl).

    This made a Wine Gallon "Reputed Pint" equivalent to 2 ⁄ 3 US liquid pint (10.66 US fluid oz.), 11.09 imp. oz, or 315 mL. Although the Imperial system was introduced in 1824, bottles of ale or beer were still sold in Reputed Pints (13.3 imperial oz) but were now based on the Imperial gallon (based on the British Ale Gallon).
