Question: Two electric motors are being considered to drive a centrifugal pump. One of the motors must be selected. Each motor is capable of delivering 60 horsepower (output) to the pumping operation. It is expected that the motors will be in use 800 hours per year. The following data are available: Motor A Motor BCapital investment $1,200 $1,000Electrical efficiency 0.92 0.80Annual maintenance $160 $100Useful life 3 years 6 years
a. If electricity costs $0.07 per kilowatt-hour, which motor should be selected if the MARR is 8% per year? Recall that 1 hp = 0.746 kW. Assume repeatability.
b. What is the basic trade-off being made in this problem?
