Particles having a size of 0.10 mm, a sphericity of 0.86, and a density of 1200 kg/m3 are to be fluidized using air at 250C and 202.65 kPa abs pressure. The void fraction at minimum fluidizing conditions is 0.43. The bed diameter is 0.60 m and the bed contains 350 kg of solids. Calculate the minimum height of the fluidized bed, the pressure drop at minimum fluidizing conditions, and the minimum velocity for fluidization.
