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.
Darcyâs law is then written as. ....................(2). This version of Darcyâs law is not useful to the petroleum engineer, but it is sometimes handy to be able to convert from hydraulic conductivity units to permeability. To obtain k in darcies, multiply K in m/s by 1.04Ã10 5.ermeability (k) is a rock property relating the flow per unit area to the hydraulic gradient by Darcyâs law, ....................(1). where: p is pressure Ï is fluid density g is gravitational acceleration z is elevation Î¼ is the dynamic viscosity.
