The product from a crystallizer is to be separated from the liquor using a centrifuge. The concentration of the crystals is 6.5% and the slurry feed rate to the centrifuge will be 5.0 m3 /h. The density of the liquor is 995 kg/m3 and that of the crystals 1500 kg/m3. The viscosity of the liquor is 0.7 mN m-2 s. The cutoff crystal size required is 5 μm. Select a suitable type of centrifuge to use for this duty.
