Six years ago, an 80-kW diesel electric set cost $160,000. The cost index for this class of equipment six years ago was 187 and is now 194. The cost capacity factor is 0.6. Solve, 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 $18,000. Determine the total cost of the 120-kW unit. b. Estimate the cost of a 40-kW unit of the same general design. Include the cost of the $18,000 precompressor.
Problem 2
Six years ago, an 80-kW diesel-electric set cost $160,000. The cost index for this class of
equipment six years ago was 187 and is now 194. The plant engineering staff was considering a
120-kW unit of the same general design to power a small isolated plant that would have cost
$211,707.
Based on the information above the plant engineering staff is considering a 100 kW unit of the
same general design to power a small isolated plant. Assume we want to add a pre-compressor,
which (when isolated and estimated separately) currently costs $13,000. Determine the total cost
of the 100-kW unit.

- Five years ago, when the relevant cost index was 135, a nuclear centrifuge cost $32,000. The centrifuge had a capacity of separating 1250 gallons of ionized solution per hour. Today, it is desired to build a centrifuge with capacity of 3500 gallons per hour, but the cost index now is 270. Assuming a power-sizing exponent to reflect economies of scale, x, of 0.72, use the power-sizing model to determine the approximate cost (expressed in today’s dollars) of the new reactor.arrow_forwardHomeowner Henry is building a fireplace for his house.
