  2. Cloud point - Wikipedia

    en.wikipedia.org/wiki/Cloud_point

    The cloud point of a nonionic surfactant or glycol solution is the temperature at which the mixture starts to phase-separate, and two phases appear, thus becoming cloudy. This behavior is characteristic of non-ionic surfactants containing polyoxyethylene chains, which exhibit reverse solubility versus temperature behavior in water and therefore ...

  3. Winter diesel fuel - Wikipedia

    en.wikipedia.org/wiki/Winter_diesel_fuel

    The Standard lists 12 climatic regions and the limits range from −3 °C to 15 °C. Ordinarily, Australian automotive diesel fuels on average have a cold filter plugging point value that is about 2 °C below the cloud point. The Standard also lists particular locations where fuel problems may possibly occur because of cold weather conditions. [10]

  4. Point cloud - Wikipedia

    en.wikipedia.org/wiki/Point_cloud

    A point cloud image of a torus Geo-referenced point cloud of Red Rocks, Colorado (by DroneMapper) A point cloud is a discrete set of data points in space. The points may represent a 3D shape or object. Each point position has its set of Cartesian coordinates (X, Y, Z).

  5. Dew point - Wikipedia

    en.wikipedia.org/wiki/Dew_point

    When the temperature is below the freezing point of water, the dew point is called the frost point, as frost is formed via deposition rather than condensation. [4] In liquids, the analog to the dew point is the cloud point .

  6. Cold filter plugging point - Wikipedia

    en.wikipedia.org/wiki/Cold_filter_plugging_point

    Cold filter plugging point (CFPP) is the lowest temperature, expressed in degrees Celsius (°C), at which a given volume of diesel type of fuel still passes through a standardized filtration device in a specified time when cooled under certain conditions. This test gives an estimate for the lowest temperature that a fuel will give trouble free ...
