Permeability can be determined by direct measurement with the help of___________
Permeability of soil can be determined by permeameters, by allowing the water to flow through soil sample under either constant head or under variable head.
Which of the following formula , cannot be used for determining the permeability of soil?
In Darcy’s equation or Darcy’s law, there is no permeability constant.
q = k i A
Hence it cannot be used for finding permeability of soil.
Coefficient of permeability of soil can be determined by which of the following method?
The coefficient of permeability can be determined by the following methods:
a. Laboratory method – constant head permeability and falling head permeability test
b. Field method –pumping-out and pumping-in test
c. Indirect methods- horizontal capillary test and consolidation test data.
Allen Hazen’s formula is given by which of the following equations?
Allen Hazen’s formula is K=CD102, where c is constant, which is taken as approximately equal to 100 when D10¬ is expressed in cm.
The unit of coefficient of absolute permeability(K) is __________
Since K has the dimension of area (i.e. [k] = [L2]),the unit of K is m2.
