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.
TDS and Electrical Conductivity. Since the electrical conductivity is a measure to the capacity of water to conduct electrical current, it is directly related to the concentration of salts dissolved in water, and therefore to the Total Dissolved Solids (TDS).he Electrical Conductivity of Water. The electrical conductivity of water estimates the total amount of solids dissolved in water-TDS, which stands for Total Dissolved Solids. TDS is measured in ppm (parts per million) or in mg/l.
