2. Wet crystals of sugar are taken from the bottom of an evaporator and charged to a centrifuge. The charge contairs 0.4 cu ft of liquor per cubic foot of dry crystals. If the crystals (4-in. thick cake) are centrifuged for 2min and the centrifuge develops 100 times the force of gravity, how much liquor will remain in the crystsis (expressed as cubic feet of liquor per cubic foot of dry crystals)
