Both pipelines will need some valve and fitting replacements in year 25. Cost data for each route is shown in Table P2.21. Notice that the undersea route has a higher initial cost due to higher installation costs and extra corrosion protection for the pipeline. However, the undersea route has cheaper security and maintenance costs which substantially reduces annual costs. The MARR for the project is 15%. Determine which route should be pursued based on a present worth analysis.arrow_forward

- Three alternatives are being considered for an air cleaning system. All three systems have a lifeof 10 years with no salvage value. System A has an initial cost of $29,000. During the first fiveyears of operation, the annual costs to operate system A are $5,000. During the second five years,the annual cost of system A increases to $16,000. System B has an initial cost of $43,000. Theannual cost to operate system B is $4,000, however, after the first year, this cost increases by$1,600 per year. System C has an initial cost of $58,000 with an annual cost of $2,400. System Crequires two upgrades: one during year 4 which costs $6,000, and the other during year 8 whichcosts $3,000. The MARR for this project is 17%.
