  2. Incapacitating agent - Wikipedia

    en.wikipedia.org/wiki/Incapacitating_agent

    Incapacitating agent is a chemical or biological agent which renders a person unable to harm themselves or others, regardless of consciousness. [1]Lethal agents are primarily intended to kill, but incapacitating agents can also kill if administered in a potent enough dose, or in certain scenarios.

  3. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    If a leak occurs, the substances to be measured come into contact with the tube in the form of vapour, gas or dissolved in water. In the event of a leak, some of the leaking substance diffuses into the tube. After a certain period of time, the inside of the tube produces an accurate image of the substances surrounding the tube.

  4. Discharge coefficient - Wikipedia

    en.wikipedia.org/wiki/Discharge_coefficient

    In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.

    en.wikipedia.org/wiki/Dimethyl_ether

    Dimethyl ether (DME; also known as methoxymethane) is the organic compound with the formula CH 3 OCH 3, (sometimes ambiguously simplified to C 2 H 6 O as it is an isomer of ethanol). The simplest ether , it is a colorless gas that is a useful precursor to other organic compounds and an aerosol propellant that is currently being demonstrated for ...

    The parts must not be anodized, as the oxide layer traps (and then outgasses) water vapor. Anodizing also makes the surface non-conducting, so that its surface will charge up in electrostatic systems. The best treatment is Alochroming, which seals the surface, makes it hard and conductive. Its outgassing rate is considerably less than non ...

    en.wikipedia.org/wiki/Ether

    A water miscible solvent often found in lithium batteries (b.p. 85 °C): Dioxane: A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed. Crown ...

  8. Starting fluid - Wikipedia

    en.wikipedia.org/wiki/Starting_fluid

    Starting fluid is sprayed into the engine intake near the air filter, or into the carburetor bore or a spark plug hole of an engine to get added fuel to the combustion cylinder quickly. Using starting fluid to get the engine running faster avoids wear to starters and fatigue to one's arm with pull start engines, especially on rarely used machines.

  9. Leak - Wikipedia

    en.wikipedia.org/wiki/Leak

    An example of a possible industrial location of a leak between two fluid systems includes a leak between the shell and tube sides in a heat exchanger, potentially contaminating either or both fluid systems with the other fluid. A system holding a full or partial vacuum may have a leak causing inleakage of air from the outside. Hazmat procedures ...
