Test: Determination Of Coefficient Of Permeability - Question 1

### Permeability can be determined by direct measurement with the help of___________

Detailed Solution for Test: Determination Of Coefficient Of Permeability - Question 1

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.

Test: Determination Of Coefficient Of Permeability - Question 2

### Which of the following formula , cannot be used for determining the permeability of soil?

Detailed Solution for Test: Determination Of Coefficient Of Permeability - Question 2

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.

Test: Determination Of Coefficient Of Permeability - Question 3

### Coefficient of permeability of soil can be determined by which of the following method?

Detailed Solution for Test: Determination Of Coefficient Of Permeability - Question 3

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.

Test: Determination Of Coefficient Of Permeability - Question 4

Allen Hazen’s formula is given by which of the following equations?

Detailed Solution for Test: Determination Of Coefficient Of Permeability - Question 4

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.

Test: Determination Of Coefficient Of Permeability - Question 5

The unit of coefficient of absolute permeability(K) is __________

Detailed Solution for Test: Determination Of Coefficient Of Permeability - Question 5

Since K has the dimension of area (i.e. [k] = [L2]),the unit of K is m2.
