Chapter 5, Problem 6P
A large induced-draft fan is needed for an upgraded industrial process. The motor to drive this fan is rated at 100 horsepower, and the motor will operate at full load for 8,760 hours per year. The motor’s efficiency is 92%. Because the motor is fairly large, a demand charge of $92perkilowatt per year will be incurred in addition to an energy charge of $0.08 per kilo-watt-hour. If the installed cost of the motor is $4,000, what is the present worth of the motor over a 10-year period when the MARR is 15% per year? (5.3)

an engineer knows that the supplier of their set-5100 laser surface metrology system used on one of their lines superseded their 5100 model with the 5105. the new model has a net cost of $420000. adding the new 5105 model to the production line would in decrease scrap rate estimated to save 630000 in the first year. the rate of return for on the set-5105 purchase is 13% MEMD IS 15% what is the opportunity cost
An integrated, combined cycle power plant produces 285 MW of electricity by gasifying coal. The capital investment for the plant is $570 million, spread evenly over two years. The operating life of the plant is expected to be 20 years. Additionally, the plant will operate at full capacity 75% of the time (downtime is 25% of any given year). The MARR is 6% per year. Solve, a. If this plant will make a profit of three 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 small company heats its building and spends $8,800 per year on natural gas for this purpose. Cost increases of natural gas are expected to be 9% per year starting
one year from now (i.e., the first cash flow is $9,592 at EOY one). Their maintenance on the gas furnace is $355 per year, and this expense is expected to increase by
12% per year starting one year from now (i.e. the first cash flow for this expense is $397.60 at the EOY one). If the planning horizon is 14 years, what is the total
annual equivalent expense for operating and maintaining the furnace? The interest rate is 15% per year.

An equivalent amount of light could be produced by sixteen 250 Watt PAR (parabolic aluminized reflector) ceiling lamps. The difference in price is $10.50 per lamp, with no difference in labor. The gymnasium is used 9 months each year. How many hours per week must the gymnasium be used in order to justify the cost difference of a 1-year payback?

- Oregon Ducks, Inc. is considering buying licenses for 12 megahertz of wireless spectrum in the 700 MHz range, which is suitable for delivering television to mobile phones. The 700 MHz signals can travel long distances and more easily penetrate walls and other obstacles. The acquisition cost is $300 million. In addition, because networks that operate in the 700 MHz range are less expensive to build than those in other portions of the spectrum, Ducks estimates annual costs of $24 million over the next 9 years and no salvage value. During the same period, the company expects to generate annual revenue of $40 million by offering television and video to mobile-phone users.

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.
