Economical solar energy and energy from fusion have been identified as two of engineering's grand challenges. While work continues on these grand challenges, conservation of energy from non-renewable sources is vital. On a practical level, installing low thermal emissivity windows (low-e windows) on buildings can contribute to energy conservation. Installing low-e windows on a small office building is estimated to cost $10,500. The windows are expected to last 9 years and have no salvage value at that time. The energy savings from the windows are expected to be $2,525 in the 1st year. After the 1st year, the savings are expected to increase by $200 each year due to escalating fossil fuel costs. MARR is 12% per year and annual worth is the preferred measure of economic worth. Part a Are the low-e windows an economically attractive investment?

The annual worth of installing the low-e windows is $ Carry all interim calculations to 5 decimal places and then round your final answer to a whole number. The tolerance is ±1.

Since many U.S. Navy aircraft are at or near their usual retirement age of 30 years, military officials want a precise system to assess when aircraft should be taken out of service. A computational method developed at Carnegie Mellon maps in 3-D the microstructure of aircraft materials in their present state so that engineers can test them under different conditions of moisture, salt, dirt, etc. Military officials can then determine if an aircraft is fine, is in need of overhaul, or should be retired. If the 3-D system allows the Navy to use one airplane 2 years longer than it normally would have been used, thereby delaying the purchase of a $20 million aircraft for 2 years, what is the present worth of the assessment system at an interest rate of 8% per year?
Wall’s Pharmacy will have to sell a new product that has an estimated revenue of $5,100 per month and costs of $1,000 per month with an initial purchase of $28,000. How long will Wall's Pharmacy have to sell a new product if the MARR is 3% per month? Wall's Pharmacy will have to sell a new product for __ months.
Your boss has asked you to evaluate the economic viability of refinancing a loan on your plant's process equipment. The original loan of $400,000 was for 7 years. The payments are monthly and the nominal interest rate on the current loan is 6% per year. As of the present time, your company has had the loan for 36 months. The new loan would be for the current balance (i.e. the balance at the end of the 36th month on the old loan) with monthly payments at a nominal interest rate of 3% per year for 4 years. A one-time financing fee for the new loan is $10,000. Your company's MARR is 9% per year on a nominal basis. Determine if the new loan is economically advantageous. The present worth of the difference between the original financing plan and the new (proposed) financing plan is $ (Round to the nearest dollar.)
A large textile company is trying to decide among three alternatives of sludge dewatering processes. The costs associated with these alternatives are shown below. Alternative Y will need an upgrade of $9700 at the end of year 2. At the end of year 2, alternative Z would be replaced with another alternative Z having the same installed and operating costs. If the MARR is 12% per year, which alternative should be chosen? Alternative Y Installed costs S68500 S48500 $33500 Annual operating costs S6000 S4000 S5000 Overhaul cost in year 2 $9700 Salvage value (S) [your student ID/10) ID +10 ID- 10 ID- 10 Useful life, years 2.
A firm is must choose to buy the GSU-3300 or the UGA-3000. Both machines make the firm’s production process more efficient which in turn increases incremental cash flows. The GSU-3300 produces incremental cash flows of $24,998.00 per year for 8 years and costs $99,590.00. The UGA-3000 produces incremental cash flows of $29,475.00 per year for 9 years and cost $126,038.00. The firm’s WACC is 8.32%. What is the equivalent annual annuity of the GSU-3300? Assume that there are no taxes.
The Engineering Economist is a quarterly journal that once cost $20 for 1 year, $38 for 2 years, or $56 for 3 years. (a) What is the IRR for subscribing for 2 years rather than for 1 year at a time? (b) What is the IRR for subscribing for 3 years rather than for 1 year at a time?
The owner of the AnJ Theater is considering two proposals for upgrading the parking ramps. The first proposal involves asphalt paving of the entire parking area. The initial cost of this proposal would be $ 35000, and it would require annual maintenance of $250 beginning 3 years after installation. The owner expects to have to resurface the theater in 10 years. Resurfacing will cost only $8000, since grading and surface preparation are not necessary, but the $250 annual maintenance cost will continue. Alternatively, gravel can be purchased and spread in the drive areas and grass planted in the parking areas. The owner estimates that 29 metric tons of gravel will be needed per year starting 1 year from now at a cost of $90 per metric ton. In addition, a riding lawn mower, which will cost $2500 and have a life of 10 years, will be needed now. The cost of labor for spreading gravel, cutting grass, etc., is expected to be $900 the first year, $950 the second year and will increase by $50…
A factory installs new machinery that saves S(x) = 1800 dollars per year. y $ per year 1800 savings S=1800- 80 x net savings cost C = 100 x Year 80x dollars per year, where x is the number of years since installation. However, the cost of maintaining the new machinery is C(x) : = 100x X (a) Find the year x at which the maintenance cost C(x) will equal the savings S(x). (At this time, the new machinery should be replaced. Round your answer to the nearest whole number.) X = years (b) Find the accumulated net savings (in dollars) [savings S(x) minus cost C(x)] during the period from t = 0 to the replacement time found in part (a). (Round your answer to the nearest whole number.)
