An engineer is trying to decide which process to use to reduce sludge volume prior to disposal. Belt filter presses (BFP) will cost $203,000 to buy and $85,000 per year to operate. Belts will be replaced one time per year at a cost of $5500. Centrifuges (Cent) will cost $396,000 to buy and $119,000 per year to operate, but because the centrifuge will produce a thicker “cake”, the sludge hauling cost to the monofill will be $37,000 per year less than for the belt presses. The useful lives are 5 and 10 years for alternatives BFP and Cent, respectively, and the salvage values are assumed to be 10% of the first cost of each process whenever they are closed down or replaced. Use PW evaluation to select the more economical process at an interest rate of 6% per year over (a) the LCM of lives, and (b) a study period of 8 years. Are the decisions the same?
An American-Australian joint venture has been contracted to provide the train cars for a 25-mile subway system using new tunnel-boring and track-design technologies. Austin, Texas was selected as the proof-of-concept site based on its variety in landscape features (hilly terrain, lake and green space areas, and relatively low precipitation) and its public environmental mindedness. Selection of either a Swiss or Japanese contractor to provide the gears and power components for the electric transfer motor assemblies resulted in two cost alternatives. as shown gives the incremental cash flow estimates (in $1000) over the expected 10-year life of the motors. Determine the number of i* values and estimate them graphically.

  • James, the plant manager at Global Foundries (GF), received estimates from two contractors to improve traffic flow and repave the parking areas at his production facility. Proposal A includes new curbs, grading, and paving at an initial cost of $250,000. The expected life of the parking lot surface is 4 years with annual costs for maintenance and repainting of strips of $3000. According to proposal B, the pavement has a higher quality and an expected life of 12 years. The annual maintenance cost will be negligible for the parking area, but the markings will have to be repainted every 2 years at a cost of $5000. The MARR is 12% per year. (a) How much can GF afford to spend on proposal B for the two proposals to break even? (b) Proposal B first cost came in at $700,000. Now, what is the breakeven initial cost for proposal A, if all other estimates are correct?

    An engineer must decide between two ways to pump concrete to the top of a seven-story building. Plan 1 requires the leasing of equipment for $60,000 initially and will cost between $0.40 and $0.95 per metric ton to operate, with a most likely cost of $0.50 per metric ton. The pumper is able to deliver 100 metric tons per 8-hour day. If leased, the asset will have a contract period of 5 years. Plan 2 is rental option that will cost $15,000 per year. In addition, an extra $15 per hour labor cost will be incurred for operating the rented equipment per 8-hour day. Which plan should the engineer recommend if the equipment will be needed for 50 days per year? The MARR is 12% per year.

    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?
  • You work for Bellevue Window Products. While performing an analysis for a new window product, you found a report from last year that provided the following information regarding the manufacture of a similar product: annual production rate = 40,000 units; selling price = $70 per unit; fixed production cost = $240,000 per year; variable production cost = $1,700,000 per year; variable selling expenses = $96,000 per year. As a first-cut, you decide to use this information to estimate (a) the breakeven production rate per year, (b) the company’s profit last year, and(c) the annual production rate that would generate a profit of $1,000,000 per year. What are your estimates? Draw the breakeven diagram and spreadsheet functions necessary to perform the analysis
    FEMA (Federal Emergency Management Agency) has ordered 25 specialized test units capable of field checking 15 separate elements in potable water inemergency situations. Thompson Water Works, Inc., the contractor, took 200hours to build the first unit. If direct and indirect labor costs average $50 perhour, and an 80% learning rate is assumed, estimate (a) the time needed to complete units 5 and 25, and (b) the total labor cost for the 25 units.
    Accurate air flow measurement requires straight, unobstructed pipe for a minimum of 10 diameters upstream and 5 diameters downstream of the measuring device. In one particular application, physical constraints compromised the pipe layout, so the engineer was considering installing the air flow probes in an elbow (Plan A), knowing that flow measurement would be less accurate but good enough for process control. This plan would be acceptable for only 2 years, after which a more accurate flow measurement system with the same costs will be available. Plan A has a first cost of $25,000 with annual M&O estimated at $4000. Plan B involves installation of a recently designed submersible air flow probe. The stainless steel probe could be installed in a drop pipe with the transmitter located in a waterproof enclosure on the handrail. The cost of this system will be $88,000, but because it is accurate, it would not have to be replaced for at least 6 years. Its maintenance cost is estimated to…
  • Oil from a specific type of marine microalgae can be converted into biodiesel that may serve as an alternate transportable fuel for automobiles and trucks. If lined ponds are used to grow the algae, the construction cost is $13 million and the M&O cost is estimated at $2.1 million per year. Alternatively, if long plastic tubes are used for growing the algae, the initial cost will be higher at $18 million, but less contamination will render the M&O cost lower at $0.41 million per year. At an interest rate of 10% per year and a 5-year project period, which system is better—ponds or tubes? Use a present worth analysis.
    EP Electric has identified two new methods to treat its cooling water. Alternative I (for inflow) would treat the raw water with a conventional reverse osmosis system so that the cycles of concentration could be increased from 5 to 20. This will result in water cost savings of $360,000 per year and chemical cost savings of $56,000 per year. The initial cost of the equipment will be $2.3 million with an operating cost of $125,000 per year. Alternative B (for blowdown) will treat the cooling tower blowdown water using a highpressure seawater reverse osmosis system to recover most of the water that is sent to an evaporation pond. This option will result in water savings of $270,000 per year. The cost of the system will be $1.2 million with an operating cost of $105,000 per year. Assuming one of the two methods must be installed, determine which is preferred on the basis of the incremental ROR value using MARR of 5% per year, which is a typically low return expected of government projects.…
    Polymer Molding, Inc. is considering two processes for manufacturing storm drains. Plan A involves conventional injection molding that will require making a steel mold at a cost of $2 million. The cost for inspecting, maintaining, and cleaning the molds is expected to be $60,000 per year. Since the cost of materials for this plan is expected to be the same as for the other plan, this cost is not included in the comparison. The salvage value for plan A is expected to be 10% of the first cost. Plan B involves using an innovative process known as virtual engineered composites wherein a floating mold uses an operating system that constantly adjusts the water pressure around the mold and the chemicals entering the process. The first cost to tool the floating mold is only $795,000, but because of the newness of the process, personnel and product-reject costs are expected to be higher than for a conventional process. The company expects the operating costs to be $85,000 for the first year and…
