Solid particles having a size of 0.18 mm, a sphericity shape factor of 0.91, and a density of 1,090.

Solid particles having a size of 0.18 mm, a sphericity shape factor of 0.91, and a density of 1,090 kg/m3 are to be fluidized using air with density of 2.374 kg/m3 andviscosity 1.85e-5 Pa.s. The void fraction at minimum fluidizing conditions is 0.51. The cross sectional area of the empty bed is 0.34 m2 and the bed contains 270 kg ofsolid. Calculate: (a) the minimum height of the fluidized bed, (b) the pressure drop at the minimum fluidizing conditions, and (c) the incipient fluidizing velocityVmf.
