- A feedstuff weighing 2 g and moisture content at 5%. When estimating the crude protein, use 82 ml of HC1 (0.01 N) (Plank volume = zero). Calculate i. The percentage of crude protein base on dry matter. ii. The percentage of crude protein base on natural (fresh) material. iii. The percentage of crude protein base on organic matter, when crude ash in the feedstuff is 0.3 g.A binary mixture with components A and B is to be separated in a distillation column to obtain 95 mol%. A as the top product. The binary mixture has a con stant relative volatility AB = 2. The column feed is a a - saturated liquid containing 50 mol % of A. Under the usual simplifying assumptions such as constant molal overflow, negligible heat loss, ideal trays, the mini mum reflux ratio for this separation is (rounded off to one decimal place)Use E5C.1(a) to Plot the data in excel. Place two data sets on the same graph: one for temp vs. x and one for temp vs y (remember, x and y are the mole fractions and they belong on the x-axis). Don’t forget to include the boiling points of the pure substances – they are data, too. Add a trendline (polynomial, 3rd order should work) to each of the coexistence lines separately. Scale the plot appropriately and use the graph to answer the questions. Then complete E5C.1(b)
