Websand; black soil losses the permeability of clay and clay losses the permeability of sand so, the measured k eq has occurred less than calculated. Case (2): In this case top most layer is clay followed by sand and black soil. The black soil decreases the permeability of sand and permeability of clay depends upon the decrease in k of sand.
Permeability is a property of foundry sand with respect to how well the sand can vent, i.e. how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases. The permeability is commonly tested to see if it is correct for the casting conditions.
