Small food particles with diameter 10^-2 mm and density 1.03 g cm^-3 are suspended in liquid of density 1.00 g cm^-3. The viscosity of the liquid is 1.25 mPa s. A tubular-bowl centrifuge of length 70 cm and radius 11.5 cm is used to separate the particles. If the centrifuge is operated at 10 000 rpm, estimate the feed flow rate at which the food particles are just removed from the suspension. ____________________
