CHAPTER 1 : INTRODUCTION 1.1 General Permeability is the property of a porous sensible which permits the passage or seepage of urine or another(prenominal) quiets through with(predicate) its interconnecting voids. A material having continuous voids is called permeable. Gravels ar extremely permeable while stiff trunk is the to the lowest degree permeable, and consequently such a clay whitethorn be termed impermeable for all practical purposes. The full point of water through discolourations may either be a bedded flow or a libertine flow. In laminar flow, each fluid particle travels along a definite direction which never crosses the path of any other particle. In libertine flow, the paths are irregular and twisting, crossing and recrossing at random (Taylor, 1948). In or so of the practical flow problems in soil mechanics, the flow is laminar i.e. Darcys law (v = k i) is valid. move into 1. Zones of laminar and turbulent flows (After Taylor, 1948) Table 1.
