ACCOUNTING AND FINANCIAL ENGINEERING - ANSWER 34.24 : (a) Let ^ to be mathematical symbol for power. From N = A = 1 year to N = B = 5 years, Q = summation of [ T / (1 + I) ^ N ] = T { summation of [ (1 + I) ^ (-N) ] } = $275 { summation of [ (1.12) ^ (-N) ] } = $275 [ (1.12) ^ (-1) + (1.12) ^ (-2) + (1.12) ^ (-3) + (1.12) ^ (-4) + (1.12) ^ (-5) ] = $991.31. Then V = P + Q = -$1000 + $991.31 = -$8.6865. (b) X = V + (summation of the values of W) = -$8.6865 + $ (11.9725 + 9.1486 + 6.5579 + 4.1811 + 2.0005) = $25.1741.

ENVIRONMENTAL ENGINEERING - QUESTION 22.2 : Biochemical Oxygen Demand (BOD) could be calculated using the formula BOD = (DOi - DOf) (Vb / Vs) where Vb = Volume of bottle in ml, Vs = Volume of sample in ml, DOi = Initial dissolved oxygen in mg / L, DOf = Final dissolved oxygen in mg / L. (a) By using a bottle of Vb = 300 ml with sample Vs = 30 ml, find the BOD if DOi = 8.8 mg / L and DOf = 5.9 mg / L. (b) By using a bottle Vb = 600 mL with sample Vs = 100 mL, find the BOD if DOi = 8.8 mg / L and DOf = 4.2 mg / L. (c) Find the average BOD = [ Answer of (a) + Answer of (b) ] / 2. (d) If the BOD-5 test for (a) - (c) is run on a secondary effluent using a nitrification inhibitor, find the nitrogenous BOD (NBOD) = TBOD - CBOD. Let TBOD = 45 mg / L and CBOD = Answer of (c).

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.4 : A university is enrolling new students of biochemical engineering degree. A long queue is formed during registration. Let L = rate of newcomers to a queue, m = number of clients served at a certain time, T = time in system. In M / M / 1 queue, let T = time waiting in a queue + service time, L = 2 / second, m = 3 / second. (a) Find the service time, A = 1 / m. (b) Calculate time waiting in a queue, B = A (L / m) / (1 - L / m). (c) What is the value of T?
