A special-purpose 30-horsepower electric motor has an efficiency of 90%. Its purchase and installation price is $2,300. A second 30-horsepower high-efficiency motor can be purchased

image text in transcribed

A special-purpose 30-horsepower electric motor has an efficiency of

90%.

Its purchase and installation price is

$2,300.

A second 30-horsepower high-efficiency motor can be purchased for

$3,200,

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=15%

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 an incremental investment of

$900

in the more efficient motor, what is the PW of the energy savings over the eight-year period? Recall that 1 hp = 0.746 kW.
