Q4) Catalyst pellets 0.2-in diameter are to be fluidized with 100,000 lb/hr of air at 1atm and 170F in a vertical cylindrical vessel. The density of the catalyst particles is 60lb/ft3 and the sphericity =0.6. If the given quantity of air is just sufficient to fluidize the solids, what is the vessel cross-sectional area? (lb/fts) (25 Marks)
