| Abstract: | Abstract The unit of permeability is Darcy, md, or unit of area. The symbol used to represent it is k, and the symbol K is used to represent mobility. Many references including some textbooks in soil mechanics contain confusion between these two terms, that is, hydraulic permeability K is used to refer to permeability k. In these books the term hydraulic permeability or coefficient of permeability is used to refer to mobility. Moreover, the symbols k and K are used in a contrary manner. Also, there is an error in the unit of hydraulic permeability. This work is a trial to clarify and correct this error. |
