  2. Limiting oxygen concentration - Wikipedia

    en.wikipedia.org/wiki/Limiting_oxygen_concentration

    Flammability diagram, green dotted line shows safe purging of an air-filled vessel, first with nitrogen, then with methane, to avoid the flammable region. The limiting oxygen concentration is shown in the lower right of the diagram.

  3. Useful conversions and formulas for air dispersion modeling

    en.wikipedia.org/wiki/Useful_conversions_and...

    Atmospheric pollutant concentrations expressed as mass per unit volume of atmospheric air (e.g., mg/m 3, μg/m 3, etc.) at sea level will decrease with increasing altitude because the atmospheric pressure decreases with increasing altitude.

  4. Flammability diagram - Wikipedia

    en.wikipedia.org/wiki/Flammability_diagram

    Triangular diagrams are not commonplace. The easiest way to understand them is to briefly go through three basic steps in their construction. Consider the first triangular diagram below, which shows all possible mixtures of methane, oxygen and nitrogen. Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen ...

  5. Fuel factor - Wikipedia

    en.wikipedia.org/wiki/Fuel_factor

    The fuel factor, f o, is the ratio of created CO 2 to depleted oxygen in a combustion reaction, used to check the accuracy of an emission measurement system. [1] It can be calculated using the equation

  6. Oxygen balance - Wikipedia

    en.wikipedia.org/wiki/Oxygen_balance

    Oxygen balance (OB, OB%, or Ω) is an expression that is used to indicate the degree to which an explosive can be oxidized, [1] to determine if an explosive molecule contains enough oxygen to fully oxidize the other atoms in the explosive.

  7. Metabolic equivalent of task - Wikipedia

    en.wikipedia.org/wiki/Metabolic_equivalent_of_task

    The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...

  8. Shunt equation - Wikipedia

    en.wikipedia.org/wiki/Shunt_equation

    Using the fact that each gram of hemoglobin can carry 1.34 mL of O2, the oxygen content of the blood (either arterial or venous) can be estimated by the following formula: = [] ( /) + PO2 is the partial pressure of oxygen and reflects the amount of oxygen gas dissolved in the blood. The term 0.0032 * P02 in the equation is very small and ...

  9. Theoretical oxygen demand - Wikipedia

    en.wikipedia.org/wiki/Theoretical_oxygen_demand

    Theoretical oxygen demand (ThOD) is the calculated amount of oxygen required to oxidize a compound to its final oxidation products. [1] However, there are some differences between standard methods that can influence the results obtained: for example, some calculations assume that nitrogen released from organic compounds is generated as ammonia, whereas others allow for ammonia oxidation to ...
