Assume that CuSO₄·5H₂0 is to be crystallized in an ideal product-classifying crystallizer. A 1.4-mm product is desired. The growth rate is estimated to be 0.2 μm/s. The geometric constant a is 0.20, and the density of the crystal is 2,300 kg/m³. A magma consistency of 0.35 m³ of crystals per cubic meter of mother liquor is to be used. What is the production rate, in kilograms of crystals per hour per cubic meter of mother liquor? What rate of nucleation, in number per hour per cubic meter of mother liquor, is needed?
