- Adhesives distribute loads across the interface, whereas fasteners create areas of localized stresses. True or Falsearrow_forwardA continuous column flash system is separating 100 kmol/h of a saturated liquid feed that is 45 mol% methanol and 55 mol% water at 1.0 atm. Operate with L/V = 1.5 and the outlet bottoms at xN = 0.28. Find the values of FL, FV, y1, and the number of equilibrium stages required. Find the value of Q used to vaporize FV. For a normal flash with the same feed and the same V/F, find the values of x and y.arrow_forwardA beer still is being used to separate ethanol from water at 1.0 atm. The saturated liquid feed flow rate is F = 840.0 kmol/h. The feed is 44.0 mol% ethanol. The saturated vapor steam is pure water with ratio of steam flow rate S to feed rate, S/F = 2/3. We desire a bottoms product that is 4.0 mol% ethanol. CMO is valid. Find the mole fraction of ethanol in the distillate vapor, yD,E. Find the number of equilibrium stages required. If the feed is unchanged and the S/F ratio is unchanged, but the number of stages is increased to a very large number, what is the lowest bottoms mole fraction of ethanol that can be obtained?arrow_forward
