A distillation column is separating phenol from p-cresol at 1.0 atm pressure. Distillate composition is 0.96 mol fraction phenol. An external reflux ratio of L/D = 4 is used, and the reflux is returned to the column as a saturated liquid. The equilibrium data can be represented by a constant relative volatility, αphenol−cresol = 1.76 (Perry et al., 1963, pp. 13–3). CMO can be assumed. The feed is on stage 8. a) What is the vapor mole fraction of phenol leaving the third equilibrium stage below the total condenser? Solve this problem using an analytical stage-by-stage calculation alternating between the operating equation and the equilibrium equation (Lewis method). b) What is the liquid mole fraction of phenol leaving the sixth equilibrium stage below the total condenser?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
