Measurement of Permeability of the Sand by Using Darcy's Law

The book deals with the action of amendment in Darcy's apparatus by suitable changes. During fabrication there is a use of different materials which are assembled to make the experimental setup to measure the permeability of sand (except coarse grained soils) by falling head method at different length of samples used. Graphs and Experimental analysis shows that compactness of the sand verses moisture content first increases at certain higher value than decreases a moisture content increase. Results obtained are almost accurate within typical permeability range which is used in petroleum geology, casting industries for making mould etc. This setup is too simple to operate with low skilled workers.
