The main factor on which the behaviour of a mass of fluidised solid depends mainly is the___________________?
Correct answer: C. Both A. and B.
- A. Fluid characteristics
- B. Particle size
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Fluidised-bed behaviour is governed by both the fluid properties, such as density and viscosity, and particle characteristics, especially size. Therefore both factors must be considered.
