A soybean flake suspension weighing a total of 100 kg contains 75 kg of inert solids and 25 kg of solution with 10% by weight of oil and 90% by weight of hexane solvent. The slurry comes into contact with 100 kg of pure hexane in a single step, so that the N value for the bottom outlet flow is 1.5 kg of insoluble solids/kg of retained solution. Calculate the amount and composition of the overflow flow Vt and the underflow Lt leaving the stage.
