a water pumping company wants to purchase an electric motor rated at 15 Hp for 1000$( 1 HP= 0.7457kw ). the service life of motor is known to be 10 years with negligible salvage value.its full load efficiency is 85%. the cost of energy is 0.08$ per kWhr. the intended of the motor is 4000 hours per year .Determine the present worth
for the total cost of owning and operating the motor at 10% interest rate

A-19,695 $
B- 26,875 $
C- 2,725 $
D- 22,994 $

could anyone solve this problem please ?

Expert Solution

Correct option is A-19,695 $

efficiency = 85%

KWatt output = 15 * 0.7457 * 0.85 = 9.5077

The present worth for the total cost of owning and operating the motor is $19695 approx.

Please don't forget to rate the answer if its helpful, thank you.
