Six years ago, an 80-kW diesel electric set cost exist140,000. The cost index for this class of equipment six years ago was 185 and is now 194. The cost-capacity factor is 0.5. a. The plant engineering staff is considering a 120-kW unit of the same general design to power a small isolated plant. Assume we want to add a precompressor, which (when isolated and estimated separately) currently costs exist19,000. Determine the total cost of the 120-kW unit. b. Estimate the cost of a 45-kW unit of the same general design. Include the cost of the exist19,000 precompressor. a. The total cost of the 120-kW unit is exist (Round to the nearest dollar.)
