A packed bed consisting of uniform spherical particles of diameter 3mm and density 4200 kg/m3, is fluidized by means of a liquid viscosity 1 mN-s/m2 and density of 1100 kg/m3. Using Ergun’s equation for the pressure drop through a bed of height L voidage ɛ as a function of superficial velocity, calculate the minimum fluidizing velocity.
