Direction: Each of the next consists of two statements, one labeled as the ‘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:
(a) Both A and R are individually true and R is the correct explanation of A.
(b) Both A and R are individually true but R is not the correct explanation of A.
(c) A is true but R is false
(d) A is false but R is true
Assertion (A): For a fully developed viscous flow through a pipe the velocity distribution across any section is parabolic in shape.
Reason (R): The shear stress distribution from the centre line of pipe upto the pipe surface increases linearly.
