Minimum fluidisation velocity for a specific system depends upon the___________________?
Correct answer: D. All A., B. and C.
- A. Particle size
- B. Fluid viscosity
- C. Density of both the particle & the fluid
- D. All A., B. and C.
Explanation
The minimum fluidisation velocity is determined by the balance between particle weight and fluid drag, so it depends on particle size, fluid viscosity, and both particle and fluid densities. Therefore all three listed factors are involved.
