Question
Each of the two pumps (ABC and XYZ) can deliver an actual amount of 100 hp to an agricultural application. Both are being evaluated in a present economy study. The selected pump will only be utilized for one year, and it will have no market value at the end of the year. Pertinent data are summarized as follows:

ABC Pump $2,900 $170 XYZ Pump $6,200 Purchase Price Annual Maintenance $510 Efficiency 80% 90%
If electric power costs $0.10 per kWh and the pump will be operated 4,000 hours per year, which pump should be chosen? Recall that 1 hp = 0.746 kW.

    A special-purpose 30-horsepower electric motor has an efficiency of 90%. Its purchase and installation price is $2,200. A second 30-horsepower high-efficiency motor can be purchased for $3,200, and its efficiency is 92%. Either motor will be operated 4,000 hours per year at full load, and electricity costs $0.10 per kilowatt-hour (kWh). MARR = 12% per year, and neither motor will have a market value at the end of the eight-year study period. a. Which motor should be chosen? b. For...
