Solid particles with size of 0.12mm, shape factor of 0.88 and a particle density of 1000kg/m3 are to be fluidized with air (MM of air is 29kg/kmol) at 2 bar (abs) and 250C. The bulk density of the solid material is 900kg/m3 and the height of the packed bed is 1.11m. The voidage at minimum fluidizing velocity is 0.042. The bed is charged with 300kg of solid material and the diameter of the empty bed is 0.62m. R= 8.314 m3∙Pa/(mol.K), g =9.81m/s2 Calculate the minimum height of the fluidized bed the pressure drop at minimum fluidizing conditions the minimum fluidizing velocity

QUESTION 3
Solid particles with size of 0.12mm, shape factor of 0.88 and a particle density of 1000kg/m3 are to be fluidized with air (MM of air is 29kg/kmol) at 2 bar (abs) and 250C. The bulk density of the solid material is 900kg/m3 and the height of the packed bed is 1.11m. The voidage at minimum fluidizing velocity is 0.042. The bed is charged with 300kg of solid material and the diameter of the empty bed is 0.62m. R= 8.314 m3∙Pa/(mol.K), g =9.81m/s2
