A. Calculate the velocity of fluidization of a catalytic bed of diameter D = 2ft and initial height Ho= 3ft. The bed is packed with solid particles of density ps = 2 g/cm³and effective diameter Dp = 0.5cm, under continuous flow of fluid of viscosity µ = 1cP and density ps = 1 g/cm³. The void fraction, ɛ, equals ɛ = 1- n/6 (cubic arrangement of particles). What power input is required at fluidization? %3D
