Question

Spherical solid particles having a size of 0.12 mm, and a density of 1000 kg/m³ are to be fluidized using air at 2.0 atm abs and 25 degree C. The voidage at minimum fluidizing condition is 0.42.

a. If the cross-sectional area of the empty bed is 0.3 m² and the bed contains 300 kg of solid, calculate the minimum height of the fluidized bed and the height when fluidization begins.

b. Calculate the pressure drop at minimum fluidizing condition.

c. Calculate the minimum velocity at minimum fluidization.
