PROBLEM 3 (20 Pts) For the given distillation process below, 10%

PROBLEM 3 (20 Pts) For the given distillation process below, 10% by mass of ethanol-water mixture is fed to the column at a rate of 10kgs. The weight of the distillate (D) is obtained to be 1/10 of the feed and its composition is 69% ethanol. Calculate: a) the mass flowrates (in kg/s) of the bottoms (B), the distillate (D) streams b) the composition (by mass) of the bottoms stream. Cooling Water 1 Distillate = ?
