Which of the following is not an advantage of fluidisation from transfer operation point of view ?
Correct answer: D. Lower fluid pumping power requirement
- A. Intimate contact of the fluid with all parts of the solid particles
- B. Prevention of particle segregation
- C. Minimisation of temperature variation
- D. Lower fluid pumping power requirement
Explanation
Fluidisation often improves contact, temperature uniformity, and resistance to segregation, but it generally requires substantial fluid pumping power to suspend the particles. Thus, lower pumping power is not an advantage.
