2. To separate a mixture of peas into two groups according to their sizes, the peas are dropped into a column of water at 20C. The average diameter of one group of peas is 6mm with a density of 1.05g/cm3, and that of the second group is 7.5mm with a density of 1.08g/cm3. Viscosity of water is 1.0mPas. Density of water is 1.0g/cm3. Determine how far the larger peas have traveled when the smaller peas travel a distance of 50cm. If design restrictions require a minimum of 60cm distance between the two groups for fluming the larger peas away from the smaller peas, what is the minimum depth of the water column?
