A distillation unit is fed with a liquid mixture containing 10% methyl alcohol (MeOH), 50% ethyl alcohol (EtOH), and, water by weight. The feed rate is at 100 kg/h. A distillate stream containing 15% MeOH, 80% EtOH is collected at 60 kg/h. At what rate will the bottom stream be collected and what is its composition?
