Test: Darcy’s Law - Question 3

Gravels are__________permeable.

Detailed Solution for Test: Darcy’s Law - Question 3

The pore size in gravel is larger, hence the gravels are highly permeable than sand which is least permeable.

Test: Darcy’s Law - Question 4

The law of flow of water through soil was first studied by___________

Detailed Solution for Test: Darcy’s Law - Question 4

In 1856, Darcy studied the law of flow of water through soil and demonstrated experimentally the laminar flow conditions.

Test: Darcy’s Law - Question 5

Which of the following equation defines Darcy’s law?

Detailed Solution for Test: Darcy’s Law - Question 5

According to Darcy’s law, the rate of flow or discharge per unit area is proportional to the hydraulic gradient .
q α i
q = K i A, where K =Darcy’s coefficient of permeability
A = total cross-sectional area.

Test: Darcy’s Law - Question 6

Coefficient of permeability or simple permeability is expressed in terms of ____________

Detailed Solution for Test: Darcy’s Law - Question 6

 As the dimension of the coefficient of permeability k are same as those of velocity. It is expressed in terms of cm/sec or m/day or feet/day.

Test: Darcy’s Law - Question 7

The co-efficient of permeability of fine sand is____________

Detailed Solution for Test: Darcy’s Law - Question 7

For fine sand, the coefficient of permeability is 0.05 to 0.001 cm /sec or
5×10-2 to 1×10-3.

Test: Darcy’s Law - Question 8

Darcy’s law is valid for only___________

Detailed Solution for Test: Darcy’s Law - Question 8

Darcy’s la of linear dependency between the velocity of flow and hydraulic agent is valid for only laminar flow conditions in the soil.

Test: Darcy’s Law - Question 9

Darcy’s law is valid as long as it is equal to or less than____________

Detailed Solution for Test: Darcy’s Law - Question 9

 In 1933, Lewis and Barnes demonstrated experimentally that Darcy’s law is valid if it is ≤ 1.

Test: Darcy’s Law - Question 10

Stiff clays are______________permeable.

Detailed Solution for Test: Darcy’s Law - Question 10

As stiff clay does not contain any porous materials, it may be termed as least permeable or impermeable.
