Coulson Fluidization

Question 1

Glass spheres are fluidised by water at a velocity equal to one half of their terminal falling velocities. Calculate:

(a) the density of the fluidised bed,
(b) the pressure gradient in the bed attributable to the presence of the particles. The particles are 2 mm in diameter and have a density of 2500 kg/m3. The density and viscosity of water are 1000 kg/m3 and 1 mNs/m2 respectively.

Answer 1

e = 0.755

Density= 1367 kg/m3

Pressure gradient= 3605 (N/m2)/m
