Intrinsic permeability formula
WebThe trend-line value at this point equals the intrinsic hydraulic permeability coefficient (q ˜ V Δ ϕ = 0 = κ H 🟉), the y-axis intercept equals the hydraulic permeability coefficient (q ˜ V I = 0 = κ H), and the slope equals the negative streaming potential coefficient (− ν 🟉). WebThe Kozeny–Carman equation (or Carman–Kozeny equation or Kozeny equation) is a relation used in the field of fluid dynamics to calculate the pressure drop of a fluid flowing through a packed bed of solids. It is named after Josef Kozeny and Philip C. Carman. The equation is only valid for creeping flow, i.e. in the slowest limit of laminar flow.
