An environmental engineer is considering three methods for disposing of a non-hazardous chemical sludge: land application, fluidized-bed incineration, and private disposal contract. The estimates for each method are below. Determine the equivalent present worth value of the LAND APPLICATION using its AW value based on 10% per year. Refer to table 2 for additional information.

Data concerning the alternative under consideration are presented below.First Cost $28,000Annual Income 7,000Annual Costs 2,500Recalibration at end of Year 4 4,000Salvage Value 2,800If the equipment has a life of eight years and MAP’s minimum attractive rate of return (MARR) is5%, what is the annual worth of the equipment?
Step by step solution for this question
Compare three alternatives on the basis of their capitalized costs at i= 8.00% per year and select the best alternative. (Include a minus sign if necessary.) Alternative E First Cost $-75000 AOC, per Year $-70000 Salvage Value $16000 Life, Years 2 The capitalized cost of alternative E is $-214212.68 X 9 and alternative G is $ -971460.48 9 F $-420000 $-14000 $66000 4 The best alternative is G G $-920000 $-5000 $750000 ∞ alternative F is $-515145.86 X
Machine D E First cost, $ −62,000 −77,000 AOC, $ per year −15,000 −21,000 Salvage value, $ 8,000 10,000 Life, years 4 6 NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Select between two metal-constricting machines. Use the corporate MARR of 15% per year with future worth analysis using tabulated factors.
