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 14% (1 HP = 746 watts = 0.746 kilowatts).

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...

Problem 6-30 (algorithmic) Question Help * Two electric motors are being considered to drive a centrifugal pump. Each motor is capable of delivering 100 horsepower (output) to the pumping operation. It is expected that the motors will be in use 2,500 hours per year and the MARR-8% per year. (1 hp 0.746 kW) a. If electricity costs SX per kilowatt-hour, calculate the annual cost of electrical power for each motor b. What cost of electricity (S/kWh) makes the two pumps...
