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).

Please show work. Thank you!
Two 180-horsepower (HP) motors are being considered for installation at a municipal sewage-treatment plant. The first costs $6,300 and has an operating efficiency of 77%. The second costs $3,600 and has an efficiency of 70%. Both motors are projected to have zero salvage value after a life of 10 years. If all the annual charges. such as insurance maintenance, etc., amount to a total of 13% of the original cost of each motor, and if...

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...

Problem 6-16 (algorithmic) Question Help A special-purpose 30-horsepower electric motor has an efficiency of 90%. Its purchase and installation price is $2,100. A second 30-horsepower high-efficiency motor can be purchased for $3,100, and its efficiency is 94%. Either motor will be operated 3,500 hours per year at full load, and electricity costs $0.09 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...

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...

6-29. Two pumps are being considered for service in Africa. Each can draw water from a depth of 50 meters and both pumps deliver 60 horsepower (output) to the pumping operation. One of the pumps must be selected. It is expected that the pump will be in use 800 hours per year. The following data are available. If electricity costs $0.14 per kilowatt-hour, which pump should be selected if the MARR is 8% per year? Recall that 1 hp =...

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:

To illustrate, consider the selection of a new water pump. The pump is to operate 800 hours per year. Pump A costs $1,900, has an overall efficiency of 82.54%, and it delivers 11 hp. The other available alternative, pump B, costs $800, has an overall efficiency of 43.86%, and delivers 12.1 hp. Both pumps have a useful life of five years and will be sold at that time. (Remember 1 hp = 0.746 kW.) Pump A will use SL depreciation...
