Annual energy cost of pump A = 60 * 0.746 * 800 * 0.14 / 0.92 = 5449.04
Annual energy cost of pump B = 60 * 0.746 * 800 * 0.14 / 0.80 = 6266.40
EUAC of pump A = 2400*(A/P, 8%,3) + 5449.04 + 320
= 2400*0.3880 + 5449.04 + 320
= 6700.24
EUAC of pump B = 2000*(A/P, 8%,6) + 6266.40 + 200
= 2000*0.2163 + 6266.40 + 200
= 6899
As annual cost of motor A is less, it should be selected
6-29. Two pumps are being considered for service in Africa. Each can draw water from a...
in a replacement analysis for a vaccum seal on a
spacecraft the following data are known about the challenger, the

for the first three years, however, it will be 3,800 in each of
years four and five, and then 4,900 in the sixth year and
increasing by 3,300 each year thereafter. The salvage value is 0 at

over the first six years is 4% per year, and over the last seven
years it will be 8% per year?

A city water and waste-water department has a four
year old sludge pump that was initially purchased for 65,000. This
pump can be kept in service for an additional 4 years, or it can be
sold for 36,000 and replaced by a new pump. The purchase price of
the replacement pump is 51,500. The projected MVs and operating
maintenance cost over the four year planning horizon are shown in
the table that follows. Assuming the MARR is 8%, A. determine...
Two 180-horsepower water pumps are being considered for installation in a farm. Financial data for these pumps are in the table below. If power cost is a flat 4 cents per kWh over the study period, determine the minimum number of hours of full-load operation per year that would justify the purchase of the more expensive pump at an interest rate of 10% (1 HP = 746 watts = 0.746 kilowatts).
