  2. Osmium compounds - Wikipedia

    en.wikipedia.org/wiki/Osmium_compounds

    Osmium dioxide is another known oxide of osmium, which can be obtained by the reaction of osmium with a variety of oxidizing agents, including, sodium chlorate, osmium tetroxide, and nitric oxide at about 600 °C. [18] [19] It does not dissolve in water, but is attacked by dilute hydrochloric acid. [20] [21] The crystals have rutile structure. [22]

  3. Air flow meter - Wikipedia

    en.wikipedia.org/wiki/Air_flow_meter

    An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...

  4. Osmium - Wikipedia

    en.wikipedia.org/wiki/Osmium

    This toxic compound is formed when powdered osmium is exposed to air. It is a very volatile, water-soluble, pale yellow, crystalline solid with a strong smell. Osmium powder has the characteristic smell of osmium tetroxide. [31] Osmium tetroxide forms red osmates OsO 4 (OH) 2− 2 upon reaction with a base.

  6. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    The cone meter is a generic yet robust differential pressure (DP) meter that has shown to be resistant to effects of asymmetric and swirling flow. While working with the same basic principles as Venturi and orifice type DP meters, cone meters don't require the same upstream and downstream piping. [ 13 ]

  7. Moisture analysis - Wikipedia

    en.wikipedia.org/wiki/Moisture_analysis

    The sensor cannot react to sudden changes in moisture, i.e., the reaction on the windings’ surfaces takes some time to stabilize. Large amounts of water in the pipeline (called slugs) will wet the surface and require tens of minutes or hours to “dry-down.”

    Osmium(IV) fluoride is an ... Osmium(IV) fluoride reacts with water. [3] OsF 4 + 2H 2 O → OsO 2 + 4HF. References This page was last edited on 29 December 2023, at ...

  9. Air sensitivity - Wikipedia

    en.wikipedia.org/wiki/Air_sensitivity

    Air sensitivity is a term used, particularly in chemistry, to denote the reactivity of chemical compounds with some constituent of air.Most often, reactions occur with atmospheric oxygen (O 2) or water vapor (H 2 O), [1] although reactions with the other constituents of air such as carbon monoxide (CO), carbon dioxide (CO 2), and nitrogen (N 2) are also possible.
