Question

Assertion (A): Constant-head permeability test is not used for fine-grained soils.
Reason (R): The lesser the permeability of the soil, lesser is the discharge.

Directions: The fol!owing items consists of two statements; one labelled as 'Assertion (A)' and the other as 'Reason (R)'. You are to examine these two statements carefully and select the answers to these items using the codes given below:
Codes:

• A. both A and R are true and R is the correct explanation of A
• B. both A and R are true but R is not a correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is C A is true but R is false

Constant head-permeability is used for coarse grained soil and not for fine-grained soils, because the discharge through the fine soils will be very small.
