The Use Of Permeability, Conductivity, Conductance And Resistance In The Description Of Water Movement In Soils And Plants, H Borg
Resource management technical reports
Permeability, conductivity, conductance and resistance are important parameters in the description of water movement in soils and plants. These terms are related, but not synonymous. Permeability is only a function of the flow pathgeometry of the medium, while conductivity also depends on the fluid involved. Conductance, in addition, takes the size of the medium into account. Resistance is simply the inverse ofconductance. By applying the definition of resistance, it isshown that Darcy's law and Ohm's law are equivalent. Conductance and resistance relate volume flow rate to a potential difference, but to relate volume flux (volume flowrate per unit area) to …
