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 $11,000. The windows are expected to last 10 years and have no salvage value at that time. The energy savings from the windows are expected to be $2,275 in the 1st year. After the 1st year, the savings are expected to increase by $225 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? Click here to access the TVM Factor Table Calculator. 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.

6.33 Liquid Sleeve, Inc. is a company that makes a sealing solution for machine shaft surfaces that have been compromised by abrasion, high pres- sures, or inadequate lubrication. The manager is considering adding a metal-based nanoparticle (Type Al or Fe) to its solution to increase the prod- uct's performance at high temperatures. The costs associated with each type are estimated. If the company's MARR is 20% per year, which nanopar- ticle type should the company select? Utilize a rate of return analysis.

An integrated, combined cycle power plant produces 280 MW of electricity by gasifying coal. The capital investment for the plant is $460 million, spread evenly over two years. The operating life of the plant is expected to be 25 years. Additionally, the plant will operate at full capacity 77% of the time (downtime is 23% of any given year). The MARR is 8% per year. a. If this plant will make a profit of two cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant? Is it a low-risk venture? b. What is the IRR for the plant? Is it profitable? a. The simple payback period of the plant is years. (Round up to one decimal place.) It's a venture. b. The IRR for the plant is %.

You are considering getting a Little Nero Caesar Salad Franchise, because your boss (the owner of a Down Under Sandwich Shoppe) seems to be making it big. The Down Under Shoppe grosses an average of $380,000 sales annually. You estimate that your business will gross an average of 95% of Down Under’s sales. You must borrow $320,000 from the bank. The bank will charge you 12% per annum interest on this loan. You also will invest $50,000 of your savings in the business (thus you will no longer receive the 4% per annum interest from this). NOTE: neither the bank loan principal nor the $50,000 of your savings you invest is an explicit or implicit cost. However, the interest paid on the bank loan is explicit and the interest foregone on your savings is implicit. Other estimated explicit expenses are: labor $130,000 per year; rent $12,000 a year; utilities $4,000 a year; and salad ingredients $140,000 a year. An explicit expense you will have to pay Little Nero, Inc., is a franchise…
Parker County Community College (PCCC) is trying to determine whether to use no insulation or to use insulation that is either 1 inch thick or 2 inches thick on its steam pipes. The heat loss from the pipes without insulation is expected to cost $1.80 per year per foot of pipe. A 1 - inch thick insulated covering will eliminate 83% of the loss and will cost $0.55 per foot. A 2-inch thick insulated covering will eliminate 92% of the loss and will cost $0.85 per foot. PCCC Physical Plant Services estimates that there are 295,000 feet of steam pipe on campus. The PCCC Accounting Office requires a 10.5%/year return to justify capital expenditures. The insulation has a life expectancy of 10 years.

Nowadays it is very important to reduce one's carbon "footprint" (how much carbon we produce in our daily lifestyles). Minimizing the use of fossil fuels and instead resorting to renewable sources of energy (e.g., solar energy) are vital to a "sustainable" lifestyle and a lower carbon footprint. Let's consider solar panels that prewarm the water fed to a conventional home water heater. The solar panels have an installed cost of $3000 and they reduce the homeowner's energy bill by $30 per month. The residual value of the solar panels is negligible at the end of their 10-year life. What is the annual effective IRR of this investment? The annual effective IRR of this investment is%. (Round to two decimal places.)
Please do not give solution in image formate thanku. Biomet Implants is planning new online patient diagnostics for surgeons while they operate. The new system will cost $300,000 to install in an operating room, $5000 annually for maintenance, and have an expected life of 10 years. The revenue per system is estimated to be $80,000 in year 1 and to increase by $10,000 per year through year 10. a) Determine NPV to see if the project is economically justified using PW analysis and an MARR of 10% per year. b) Insert a Triangle distribution with minimum at $8000, average 10,000 and maximum at 12000 as the input distribution for the revenue increase. Perform Monte Carlo Simulation and discuss the results.

Brooke is evaluating two alternatives for improving the exterior appearance of her Victorian-style house that she is remodeling inside. She plans to keep this as her home for 20 more years. The house can be completely painted at a cost of $17,500. The paint is expected to remain attractive for 5 years, at which time repainting will be necessary. Every time the building is repainted (i.e., in years 5, 10, and 15), the cost will increase by 20% over the previous time. As an alternative, the exterior can be covered with a vintage-appearing vinyl-coated siding now and again 10 years from now at a cost 31% greater than the present cost of the siding. At a MARR of 10% per year, what is the maximum amount that Brooke should spend now on the siding alternative so that the two alternatives will just break even? Solve using factors. The maximum amount that Brooke should spend now on the siding alternative is $ Note:- Do not provide handwritten solution. Maintain accuracy and quality in your…
Please use a financial calculator to solve. Be sure to list your steps. You are evaluating two different silicon wafer milling machines. The Techron I costs $237,000, has a three-year life, and has pretax operating costs of $62, 000 per year. The Techron II costs $ 415,000, has a five - year life, and has pretax operating costs of $ 35,000 per year. For both milling machines, use straight - line depreciation to zero over the project's life and assume a salvage value of $39, 000. If your tax rate is 21 percent and your discount rate is 8 percent, compute the EAC for both machines. (Your answer should be a negative value and indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
