Darcy permeability collagen

WebJan 4, 2024 · Permeability: is a measure of a rock’s ability to conduct fluids. shows how the permeability of a rock sample can be measured. A fluid of known viscosity is pumped through a rock sample of known cross-sectional area and length. The pressure drop across the sample is measured through pressure gauges. The unit of permeability is the Darcy. WebWith both methods, the interstitial fluid of collagen gels was expelled under a pressure load, resulting in compressed collagen gels that were denser than the starting gels. The permeability of collagen gels was determined using Darcy’s Law. In the vertical apparatus, a changing height of fluid pushed water through and compressed a collagen ...
