A bed is composed of particles that have a density of 1.31 g/cm3 and an average size of 12.8 mm. Assume spherical beads and am = 0.3. Calculate the following: a) minimum fluidizing velocity using water (in mm/s) b) particle Reynolds number at the start of Fluidized Bed stage c) terminal settling velocity (m/s) correction: units should be mm/s
