A cylindrical tank with inner diameter 2.0 m is designed to operate as a fluidized bed reactor for a heterogeneous catalytic reaction. The tank is loaded with a random packing of cubic particles to a height of 4.0 m with voidage 0.4 before the fluidization process. The density and length of each side of the cubic particles are 2600 kg m-3 and 1.0 cm respectively. During operation, a liquid reactant with density 1000 kg m-3 and viscosity 1.0 x 10-3 Pa·s is passed uniformly upwards through the bed to fluidize the particles. Determine the inlet superficial velocity U that needs to be applied to achieve a bed height of 6.0 m during operation of the fluidized bed reactor.
