Answer to Question #155929 in General Chemistry for simsim

Question

small food particles with diameter 10^-2mm and density 1.03g/cm3 are suspended in a liquid of density 1.00 g/cm3. The viscosity of the liquid is 1.25mPa s. A tubular-bowl centrifuge of length 70cm and radius 11.5cm 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.

Answer 1

K=4n^2r = 4 x 10000 x 10000x 11.5 = 4,6e9.
