QUESTION 1 Spherical catalyst pellets 4mm in diameter are to be fluidized with nitrogen at 101.3kPa at 600C. The density of the catalyst particles is 960 kg/m3. The molecular weight of nitrogen is 29kg/kmol. If it is assumed that the point of incipient fluidization is reached at emf(minimum fluidizing velocity)=0.430 , calculate the minimum fluidization velocity in the vessel. Nitrogen is considered here to be an ideal gas with frictional force=0.0000207 Ns/m2. R =8.314 m3∙Pa/(mol.K), g =9.81m/s2
