A fluidized bed with a diameter of 0.8m and height 3.5m, is used to process 150.5 × 10³cₘ₃/ₛ of gaseous reactant. per second. The disengaging length of the bed is 2m. The catalysts particles are cylindrical in shape with an average diameter of 150μ.

Estimate the Reynolds number of flow of the fluid and hence the minimum fluidization velocity in the bed.
