The uniformity of a gas fluidised bed depends upon the _______________ of the solid particles?
Correct answer: C. Both A. and B.
- A. Size
- B. Surface properties
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Uniform fluidisation is strongly affected by particle size and by surface characteristics such as roughness and cohesiveness. These properties control how evenly gas passes through and suspends the bed.
