Determination Permeability Coefficient from Piezocone

Determination of Permeability from Damping

Determination of microvessel permeability and tissue diffusion coefficient of solutes by laser scanning confocal microscopy.

Interstitium contains a matrix of fibrous molecules that creates considerable resistance to water and solutes in series with the microvessel wall. On the basis of our preliminary studies, by using laser-scanning confocal microscopy and a theoretical model for interstitial transport, we determined both microvessel solute permeability (P) and solute tissue diffusion coefficient (D) of alpha-lacta...

Determination of Principal Permeability Directions in Reservoir Rocks from Micro-CT Data

The routine measurement of direction-dependent reservoir rock properties like permeability often takes place along the axial direction of core samples. As permeability is a tensor property of porous materials, it should be fully described by a tensor matrix or by three main permeabilities in principal directions. Due to compaction, cementation, and other lithification processes, which take plac...

Determination of a Distribution Coefficient

Environmental chemistry is a new field of study in many chemistry departments and only three published summaries of environmental laboratory experiments are available (1–3). While these laboratory manuals contain excellent experiments for the training of students in environmental monitoring, relatively few standardized procedures have been published for broader issues such as the measuring of f...

Determination of Permeability from Impedance Measurement Using Vector Network Analyzer

This study treats the optimised one-port (reflection coefficient) and two-port (shunt-through/series-through) measurement methods for complex permeability determination of solid soft magnetic materials using a vector network analyzer (VNA) at frequencies from 9 kHz to 6.5 GHz. The principle of measurement methods, the relationships of measured phasor voltage ratio (Sparameter) to complex impeda...
