ACCOUNTING AND FINANCIAL ENGINEERING - ANSWER 34.9 : (a) P (1) = P (2) = P (3) = P (4) = P (5) = P (6) = 1 / 6. (b) Average score of D = (1 + 2 + 3 + 4 + 5 + 6) / 6 = 3.5. (c) Expected value Sn = n (average score) = 3.5 n. (d) D* (D = 1) = 1 - 3.5 = - 2.5, D* (D = 2) = 2 - 3.5 = - 1.5, D* (D = 3) = 3 - 3.5 = - 0.5, D* (D = 4) = 4 - 3.5 = 0.5, D* (D = 5) = 5 - 3.5 = 1.5, D* (D = 6) = 6 - 3.5 = 2.5. (e) Sn = 3.5 n + nD*. (f) Expected value of D* = average of D* = [ D* (D = 1) + D* (D = 2) + D* (D = 3) + D* (D = 4) + D* (D = 5) + D* (D = 6) ] / 6 = (- 2.5 - 1.5 - 0.5 + 0.5 + 1.5 + 2.5) / 6 = 0.

Question 43 - In a non-dilute absorber, the inlet gas stream consists of 8 mol % carbon dioxide in nitrogen. By contact with room temperature water at atmospheric pressure, 65 % of the carbon dioxide from a gas stream has been removed. (a) Find the mole ratio of carbon dioxide and nitrogen gases at inlet and outlet gas streams. (b) The Henry’s Law provides y = 1640 x for carbon dioxide in water. Find the mole ratio when x = 0.0000427. Mole ratio is y / (1 - y) for y.
