The alternatives for an engineering project to recover most of the energy presently being lost in the primary cooling stage of a chemical processing system have been reduced to three designs. The estimated capital investment amounts and annual expense savings are as follows: Table 3: Table for Problem 4; all monetary amounts are given in $ 0 ER1 Design ER2 1 ved vers lliw doum -$ 98,600 +$ 25,800 -$115,000 +$ 29,000 ER3 +$ 81,200 +$ 19,750 2 (zining 21) Sta 3 =6% G = $150 A = $19,750 4 5 6 +$ 34,526 +$ 29,750 Note (a): After year 1 for ER1, the annual savings are estimated to increase at a growth rate of 6% per year. Note (b): After year 1 for ER2, the annual savings are estimated to increase uniformly by $150 per year Note (c): For ER3, there is a uniform sequence of annual savings of $19,750 per year +$ 19,750 Assume that the MARR is 12% per year, the study period is 6 years, and the market value is 0 for all three designs. Apply an incremental analysis method to determine the preferred alternative.
