Particles having a size of 0.1 mm, Sphericity of 0.86 and a density of 1200 kg/m³ are to be fluidized using air at 25ºC and 2.02 bar absolute pressure. The void fraction at minimum fluidizing condition is 0.43. The bed diameter is 0.6 m and the bed contains 350 kg of solids. Viscosity of air = 1.85 ×10^-5 kg/ms.

 a. Calculate the minimum height of the fluidized bed. 

b. Calculate the pressure drop at minimum fluidizing conditions. 

c. Calculate the minimum velocity for fluidization. 

d. Using 4.0 times the minimum velocity, estimate the porosity of the bed.
