  • Is there a definition of light/medium/heavy aircraft?

    (E) Medium: Small commuter aircraft including business jets weighing more than 12,500 up to 41,000 lbs such as the Embraer 120 or the Learjet 35; and (F) Small: Small, single, or twin engine aircraft weighing 12,500 lbs or less such as the Beech 90 or the Cessna Caravan. Unknown; refers to unspecified equipment.


  • 1.2: Classification of Matter - Chemistry LibreTexts

    To classify matter. Chemists study the structures, physical properties, and chemical properties of material substances. These consist of matter, which is anything that occupies space and has mass. Gold and iridium are matter, as are peanuts, people, and postage stamps. Smoke, smog, and laughing gas are matter.



  • Colloids - Chemistry LibreTexts

    To be classified as a colloid, the substance in the dispersed phase must be larger than the size of a molecule but smaller than what can be seen with the naked eye. This can be more precisely quantified as one or more of the substance's dimensions must be between 1 and 1000 nanometers.


  • Colloids - Chemistry LibreTexts

    A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids.

  • 13.1 Types of Waves - Physics | OpenStax

    The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling. However, light is not a mechanical wave; it can travel through a vacuum such as the empty parts of outer space. A familiar wave that you can easily imagine is the water wave.


  • 13.1 Types of Waves - Physics | OpenStax

    Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling.


  • Ventilation for Acceptable Indoor Air Quality - ASHRAE

    tables classify air from a variety of space types and in some specific airstreams. The classifications are based on contami-nant concentration and odor intensity. For locations that are not listed in the tables, the air classification of the listed space or airstream that is most similar in terms of occupant activi-


  • Understanding ISO classes for compressed air quality

    Specifically, that means that the dew point of class 1 air has to be at least -70°C while class 9 air can contain between 5-10 g/m 3 of water and/or water vapor. Finally, the ISO class for oil is determined by the oil content in mg/m 3. Class 1 calls is required to contain no more than 0.01 mg of any type of oil, while class 4 air can have 500 ...


  • Air classification - ScienceDirect

    Air classification, also known as air elutriation, uses air as the medium to carry and separate solid particles into two or more groups with different particle sizes by a combination of mechanical forces, such as centrifugal, drag, gravity, or collision (Holdich, n.d.). An air classifier typically consists of a vertical tube that moves air at a ...
