1 Hydraulic conductivity, a property of a porous material's ability to transmit water. 2  Thermal conductivity, the intensive property of a material that indicates its ability to conduct heat.  Rayleigh conductivity, describing the behavior of apertures concerning the flow of a liquid or gas.
Conductivity is the measure of a materialâs ability to conduct an electric current. In ocean sciences, the electrical conductivity of seawater is used as an indication of salinity. The saltier the water, the higher the conductivity will be.Seawater salinity can be calculated from measured values of conductivity and temperature. Salinity refers to the amount of salts dissolved in water, expressed as parts per thousand, or ppt.This corresponds to the amount of salt in grams dissolved in 1000 grams of water. However, salinity is difficult to measure directly and is generally calculated from conductivity and temperature measurements.he saltier the water, the higher the conductivity will be.
