Design a distillation column for the separation of a binary mixture consisting of ethanol and water. The feed mixture contains 40 mol% ethanol and 60 mol% water, and the desired product purity is 95 mol% ethanol. The feed rate is 1000 kg/hr and the column should operate at atmospheric pressure. Calculate the number of theoretical plates required to achieve the desired separation and determine the corresponding height and diameter of the column.
