Question

Assertion (A): Flow net is dependent on the permeability of soil through which flow is taking place.
Reason (R): The flow net is useful in finding the discharge.

Directions: The following 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 D A is false but R is true

(d)
Flow net depends upon boundary condition, and not on the permeability of soil. Flow net is useful in finding the seepage discharge, uplift pressure, exit gradient etc.
