QUESTION 2 Particles of density 1200kg/m3 are fluidized with air at 250C and 203KPa (abs). The shape factor is 0.90. The void fraction at emf minimum fluidizing conditions is 0.43. The bed diameter is 0.60m and it contains 350kg of solids. The bulk density of the solids, is 1150kg/m3 and the viscosity of air is 1.845x10-5Pa.s ( ). Air is considered here to be an ideal gas. R= 8.314 m3∙Pa/(mol.K), g =9.81m/s2 Calculate 2.1 The minimum height of the bed 2.2 The pressure drop at minimum fluidizing conditions 2.3 The minimum fluidizing velocity
