Transcribed Image Text:8. A centrifuge with a bowl which is 500 mm long and has an inside radius of 50.5 mm is
to be used to separate crystals from a dilute aqueous mother liquor. The optimum
speed of rotation for the centrifuge is 60,000 rpm, and the discharge weir is adjusted so
that the depth of liquid at the bowl wall is 38.5 mm. The crystals are approximately
spherical and none are smaller that 2 x 10 m in diameter. The maximum volumetric
flow rate in m³/s of the mother liquor that can be processed by this centrifuge if all the
crystals have to be removed is
a. 0.054
b. 0.024
c. 0.154
d. none of these
