Question: Problem 2. Catalyst pellets 5-mm in diameter are to be fluidized with 45,000 kg/h of air at 1 atm and 80oC in a vertical cylindrical

Problem 2. Catalyst pellets 5-mm in diameter are to be fluidized with 45,000 kg/h of air at 1 atm and 80oC in a vertical cylindrical vessel. The density of the catalyst particles is 960 kg/m3 ; their sphericity is 0.86. The given quantity of air is just sufficient to fluidized the solids, what is the vessel diameter? Assume mf = 0.45
