Permeability chart
WebAll coefficients of permeability are normalized to 20 o C since the viscosity of a fluid depends on the temperature at which it is. As stated previously, the viscosity of a fluid will affect its ability to flow through a soil. A porous … WebJun 3, 2015 · Granberry and Keelan published a set of curves relating permeability, porosity, and "critical water" saturation (S ciw) for Gulf Coast Tertiary sands that frequently are poorly consolidated. Their chart, originally presented with S ciw as a function of permeability with porosity as a parameter, is transposed into log(k)-Φ coordinates in Fig. 1.
