Down 2. Correct density to be used in fluidisation calculations 4. Opposes the motion between the particle and the fluid media 5. A general equation that can be used to describe solid particles' movement in packed bed region 9. An excellentadvantage of a fluidized bed 10. It's required in order to be able to compute the fluidized bed height 2. A fluidized bed s very commonly used in this industry 14. Region just the bed surface in which coarse particles fall back down 16. An emerging new fluidisatien process 17 A type of force that acts on a particle ta a this region, terminal velocity is directly proportional to the square root of the particle diameter 1. An advantage that a fluidized bed has for best chemical reaction 3. A physical process which uses a fluidized bed 6. s needed to aid movement of a particle in a fluid medium 7. Shows the relationship between drag coefficient and the spheres Reynolds number 8. A sudden increase in gas flow rate in a bedcauses this 9. Non-bubbling fluidzation is also known as 11. ncrease n bed yoidage with fluidizing velocity is referred to as B. "Father" of the classification of powders B. One of the four regions that can be identified for a motion of a sphere in a fluid B. An example of a troical coarse solid found in one of the four (4) powder classifications
