2. 1000 kg/h of a mixture containing 40% methanol (by mass) and 60% (by mass) water is distilled. Product streams leave the top and the bottom of the distillation column. The flow rate of the bottom stream is 623.656 kg/h, and the overhead stream contains 98% methanol by mass. Calculate the following. 15 points a. Mass fraction of methanol in the bottom product b. Percent water in the bottom product c. Molar flow rates of the bottom products

This is a subjective question, hence you have to write your answer in the space provided. An exterior wall of house may be approximated by a 100mm layer of common brick ($K = 0.7 \frac{W}{mK}$), followed by a 40 mm layer of gypsum plaster ($K = 0.48 \frac{W}{mK}$). What thickness of loosely packed rock wool insulation ($K = 0.065$) should be added to reduce the heat loss through the wall by 75%. Assume the inside air at 20 $^\circ$C while the ambient air at 35 $^\circ$C. Take heat transfer coefficient on both side as 15 $\frac{W}{m^2K}$. [5]
