400 kg cylinders 50% in 20 mm size, 40% in 40 mm size and 10% in 50 mm size shaped particles will be fluidized using air at 25 C and 2 atm pressure. Under minimum fluidization conditions, the void fraction is 0.50. Bed diameter 0.5 m and solid volume of particles 0.35 m^3 type = 1.845 x 105 Pa s, = 2.374 for air at 2 atm and 25 C kg/m^3

a-)Calculate the minimum height of the fluidized bed

b-)Calculate the pressure drop at the minimum fluidization condition

c-)Calculate the minimum velocity for fluidization?

d-)1m length if the clearance fraction of the bed is 0.7 when using 3 times the minimum speed Calculate the pressure drop per
