Discussion
Assertion (A): Dilute phase pneumatic conveying is the gentlest way to move a fragile product.
Reason (R): Impact damage at bends rises with the square of the conveying velocity.
Select the correct answer from the options below.
Answer: C
Correct answer: A is false but R is true
The reason is true and it is exactly why the assertion is false. Dilute phase conveying works by keeping particles suspended at high velocity, and impact damage at bends grows with the square of that velocity, so it is one of the harshest methods rather than the gentlest. Dense phase, which moves material slowly in plugs, is the gentle pneumatic option.
