conductivities, plural;
  1. The degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity

  2. The rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance

  1. (conductivity) conduction: the transmission of heat or electricity or sound
  2. (Conductivity ... (Thermal)) The quantity of heat that flows through a material measured in heat units per unit time per unit of cross-sectioned area per unit of length, (electrical) the quantity of electricity that is transferred through a material of known cross-section and length.
  3. (Conductivity) The electrical property of a sheet of paper which enables it to attract charged toner. Low conductivity can result in poor image quality in digital systems.
  4. (CONDUCTIVITY) Reciprocal of volume resistivity; the conductance of a unit cube of any material.
  5. (conductivity) The rate at which heat is transmitted through a material.
  6. (Conductivity) The measure of a metal target's ability to allow eddy current generation on its surface.
  7. (Conductivity) (electrical) - the property of a water sample to transmit electric current under a set of standard conditions. It is the inverse of resistance and expressed in units of Siemens
  8. (Conductivity (Thermal)) This is a positive constant, k, that is a property of a substance and is used in the calculation of heat transfer rates for materials. ...
  9. The electrical conductivity of water is measured in micro Siemens/cm and is the traditional indicator for mineral deposits. Pure water is not a good conductor of electricity, dissolved ions increase conductivity.
  10. Conductivity refers to the ability of an electric current to flow through a particular material.
  11. (CONDUCTIVITY) A property of fountain solutions that must be controlled along with pH.
  12. (CONDUCTIVITY) the ability to serve as a channel or pathway for the flow of heat, sound, or electricity
  13. (Conductivity (dB)) When precision machinery is supported by vibration insulators, the proportion of the base frequency transferred to machinery is called the vibration conductivity. A dB value is often used to indicate conductivity. ...
  14. (Conductivity (k)) The quantity of heat that will flow through one square foot of homogeneous material, one inch thick, in one hour, when there is a temperature difference of one degree Fahrenheit between its surfaces.
  15. (Conductivity) A measure of the ability of water to pass an electric current.  Conductivity in water is affected by the presence of inorganic dissolved solids such as chloride, sulphate and phosphate anions, or sodium, magnesium, calcium, iron and aluminium cations. ...
  16. (Conductivity) An electrical property of seawater which depends on the amount of dissolved materials (primarily NaCl). Measures of conductivity can be used (with other variables) to calculate seawater’s salinity.
  17. (Conductivity) An indication of the amount of dissolved ions (for example: salt, metals) present in the water. It is determined using a meter that measures how easily electricity can flow through the water sample. ...
  18. (Conductivity) How easily something allows electric current to pass through it. If a substance is a good conductor (highly conductive), for example copper or brass, it will allow electrons to pass freely through it, offering only minor resistance.
  19. (Conductivity) The capacity of living matter to conduct action potentials.
  20. (Conductivity) The ratio of electric current to the electric field in a material. Passage of electric charge which can occur a variety of ways such as passage of electrons or ionized atoms.
  21. (Conductivity) This refers to the ability of a water to convey a current between dissimilar metals. The higher the level of Dissolved Solids, the greater the level of conductivity. This is significant as it allows corrosion to take place.
  22. (Conductivity) Used as an approximate measurement of mineral content. Units commonly used as micro mhos/cm.
  23. (Conductivity) the ease with which a me\aterial transmits an electric current. A high conductivity indicates a solution with a high charged ion content, a property sometimes used to detect ARD.
  24. Conductivity is the scale by which one determines the strength of a nutrient solution. Pure, unadulterated water actually does not conduct electricity. But as salts that are found in plant nutrients are dissolved the water, the solution begins to be able to conduct electricity. ...
