You want to fluidize a bed of solid particles using water. The particles are cubical, with a length on each side of 1/8 in. and on a SG of 1.2.

(a) What is the sphericity factor for these particles, and what is their equivalent diameter?

(b) What is the approximate bed porosity at the point of fluidization of the bed?

(c) What velocity of water would be required to fluidize the bed?

(d) What velocity of water would sweep the particles out of the bed?
