McCabe Thiele Efficiency (Wankat 1E, 6D7) We are separating methanol and

McCabe Thiele Efficiency (Wankat 1E, 6D7) We are separating methanol and water in a distillation column with a total condenser and a partial reboiler. Reflux is a saturated liquid, and constant molal overflow can be assumed. Feed is a saturated liquid of composition 0.6 and flow rate of 500moles/hr. Distillate composition is xD=0.92, and bottoms composition is xB=0.04. The external reflux ratio L/D=1.0. The partial reboiler acts as an equilibrium contact. The stages in the column have Murphree vapor efficiencies of 0.75 . Find the number of real stages needed and the optimum feed plate location in real stages

If a person discounts utility from future periods, her preferences are time-inconsistent because she does not value utility in all periods equally.

According to the hot-brain/cold-brain model, individuals usually have time-consistent preferences but sometimes lapse momentarily into a time-inconsistent frames of mind.

There is a massive body of evidence that humans prefer a fixed amount of utility now to that same amount of utility later.
