The Capillarity-Permeability Test
1 - Question
The capillarity-permeability test may be also called as ___________
a) Vertical capillarity test
b) Horizontal capillarity test
c) Capillary test
d) Coefficient of permeability test
View Answer
Explanation: The apparatus used in capillary-permeability test is horizontal; hence it can be also called as horizontal capillarity test.
2 - Question
The capillary-permeability test, is used to determine ___________
a) Coefficient of permeability and Capillary test
b) Degree of saturation
c) None of the mentioned
d) All of the mentioned
View Answer
Explanation: The capillarity-permeability test or the horizontal capillarity test is used to determine the coefficient of permeability K as well as the capillarity test hc of the soil sample.
3 - Question
The bedding planes of soil layers in soil mass may be __________
a) Horizontal
b) Vertical
c) Inclined
d) All of the mentioned
View Answer
Explanation: In nature, soil may consist of several layers deposited one above the other. Their bedding planes may be horizontal, inclined or vertica.
4 - Question
Each layer of soil layer has its own value of ___________
a) Degree of saturation
b) Coefficient of permeability
c) Capillary head
d) All of the mentioned
View Answer
Explanation: Since layer of soil is assumed to be homogeneous and isotropic, each layer has its own value of coefficient of permeability.
5 - Question
The average permeability of soil deposits depends on __________
a) Direction of flow
b) Coefficient of permeability
c) Moisture content
d) Saturation of the soil
View Answer
Explanation: The average permeability of the whole soil deposit will depend upon the direction of flow with relation to the direction of bedding planes.
6 - Question
The degree of saturation in capillarity-permeability test can be found out by ___________
a) Known dry mass of soil
b) Taking wet mass of soil
c) Finding the porosity
d) All of the mentioned
View Answer
Explanation: The degree of saturation can be found out by taking the wet mass of the soil sample at the end of the test.
7 - Question
The saturation in capillary-permeability is assumed to be ___________ percentage.
a) 0
b) 50
c) 75
d) 100
View Answer
Explanation: The saturation is assumed to be 100 % so that the formula nvs=Ki is derived from Darcy’s law.
8 - Question
The possible directions of flow of the soil deposit with respect to the bedding planes are ___________
a) Parallel and Perpendicular
b) Inclined
c) None of the mentioned
d) All of the mentioned
View Answer
Explanation: There are two possible cases of flow, one is parallel to the bedding plane and another is perpendicular to the plane.
9 - Question
The hydraulic gradient (i), used in capillary-permeability test is ____________
a) h0+hc/x
b) h0/x
c) h0+hc
d) hc/x
View Answer
Explanation: The hydraulic head lost in causing of flow = h0+hc Therefore, hydraulic gradient = h0+hc/x.
