In this article we will discuss about:- 1. Definition of Permeability 2. Darcy's Law (1856) of Permeability 3. Capillarity-Permeability Test 4. Permeability of Stratified Soil Deposits. Definition of Permeability: It is defined as the property of a porous material which permits the passage or seepage of water (or other fluids) through its interconnecting voids. A material having continuous voids is [...]
Determination of Coefficient of Permeability in Laboratory: 1. Constant Head Permeability Test (Coarse Grained): Water flows from the overhead tank consisting of three tubes – The inlet tube, the over-flow tube and the outlet tube. The constant hydraulic gradient i causing the flow is the head h (i.e., difference in water levels of the overhead and bottom tanks) divided by [...]
