Directions: The following items consist of two statements
labeled Assertion A and Reason R. You are to examine each statement carefully
and decide if the Assertion A and Reason R are individually true and if so,
whether the Reason R is a correct explanation of Assertion A. Select your
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

 (d) A is false but R is true

Assertion (A): In the equation  for laminar flow through
a pipe of diameter d, the term V (mean velocity) is given by

                               

Reason (R): The term f (friction factor) in the above equation
equals 64/Re, where Re is the Reynolds number.
