A bed of spherical glass beads (density 
, diameter 1 mm , bed porosity 0.5 ) is to be fluidized by a liquid of density 
and viscosity 0.1 Pa.s. Assume that the Reynolds number based on particle diameter is very small compared to one. If 
, then the minimum velocity (in 
) required to fluidize the bed is
