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.
Pure water has a resistance of 18.2 Mohm*cm 5. Resistivity decreases as the ionic concentration in water increases. A fun way to remember that resistivity and conductivity are reciprocals (1/measurement) is in the unit name â mho and ohm are the same letters, in reverse.hile freshwater sources have a low conductivity and seawater has a high conductivity, there is no set standard for the conductivity of water. Instead, some organizations and regions have set limits on total dissolved solids for bodies of water 14,37.
