 Question 6 Catalyst pellets 0.2 in diameter are to be fluidized

Question 6 Catalyst pellets 0.2 in diameter are to be fluidized with 100,000lb/hr of air at 1 atm and 170.F in a vertical cylindrical vessel. The density of the catalyst particles is p=60lbm/ft3. a. If the given quantity of air is just sufficient to fluidise the solids, assume RE > 1000 so inertial effects are dominant and verify if the assumption is correct. (13 marks) b. Define P as a function of height of the cylindrical vessel (L) (12 marks) Data: mf=0.45f=8.6106ftslbS=0.6M(molarmassofdryair)=28.9g/mol
