WebOct 26, 2016 · Darcy’s law describes the relationship between the instantaneous rate of discharge through a porous medium and pressure … 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.
