Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Velocity of air inside a suction hose conveying granular material will be higher than the terminal velocity of the material.
Reason R: Terminal velocity of a particle is equal to the air velocity at which a particle remains suspended in a column of air.
In light of the above statements, choose the correct answer from the options given below

• 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 the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Hint:

To transport particles vertically, the air velocity must be about 2 to 3 times their terminal velocity to ensure stable pneumatic transport and prevent blockages.

Answer 1

The Correct Option is A
