That is a fluidized bed reactor containing 15000 kg of sand (2700 kg/m3 density and approximate 0.2 mm in diameter) is experiencing an air flow at 300 ºC. If the entering air is at 20 atm and its viscosity can be assumed to be 0.021 mPa.s.

Determine:

a) The minimal porosity for fluidization if the reactor diameter is 2 m.

b) The minimal height of fluidized bed,

c) The pressure drop,

d) The minimal fluidization.
