An engineer has the option of deciding the number of turbines for the power plant he/she works at. Fixed costs and potential power output range are as follows: Number of Turbines Total annual Corresponding power fixed cost (USD) output range (MW) 1 9600 0-300 2 15000 301-600 3 20000 601-900 Variable cost is 10 USD/MW and revenue is 40 USD/MW The breakeven point for 1-turbine system is: MW The breakeven point for 2-turbine system is: MW The breakeven point for 3-turbine system is: MW If the demand is below 300 MW, does it make sense to build a turbine? If the demand is 580 MW, how many turbines are needed? If the demand is 620 MW, would you use the 3-turbine system? If projected annual demand is between 580 and 660 MW, how many turbines should be built?
Check my work Two processes can be used for producing a polymer that reduces friction loss in engines. Process T will have a first cost of $740,000, an operating cost of $98.000 per year, and a salvage value of $80,000 after its 2-year life. Process W will have a first cost of $1,180,000, an operating cost of $25,000 per year, and a $120,000 salvage value after its 4-year life. Process W will also require updating at the end of year 2 at a cost of $90,000. Which process should be selected on the basis of a present worth analysis at a MARR of 12% per year? The present worth of process T is $- The process selected on the basis of the present worth analysis is process W and the present worth of process W is $-

You received a memo that you are appointed as the team leader for a new commercial building project. Based on the estimation, if your team will be using a steel, it will cost 80,000 per month and 145000 cost if glass. For the plan A, it has an annual maintenance cost is 25000, 1000 repair cost every 2 years and a salvage value of 3000 after 15 years. For the plan B, the repair cost is 3500 every 3 years, annual maintenance cost of 30000 and a salvage value of 1000 after 20 years. Compute for the capitalized cost if the money is worth 8% compounded annually and choose the best material for the project. CC Plan A = (2 decimal places ) CC Plan B = (2 decimal places )

BVM manufactured and sold 25,000 small statues this past year. At that volume, the firm was exactly in a breakeven situation in terms of profitability. BVM’s unit costs are expected to increase by 30% next year. What additional information is needed to determine how much the production volume/sales would have to increase next year to just break even in terms of profitability? (a) Costs per unit (b) Sales price per unit and costs per unit (c) Total fixed costs, sales price per unit, and costs per unit (d) No data is needed, the volume increase is 25, 000 + 25, 000(0.30) = 32, 500 units.
