Question 4) what is the cost per operating hour for this motor considering all cost items?

pls help with this engineering economics!!!!!?!?!?!??

A special type of elecric motor is under cons deration for a job shop, inancial information and operating characteristics of the motor are 4500 10 yaira Sahhage value Operaing and Maintannce Coat par yaar output Eiciancy 5300 Assume that the motor will be operated 2,000 hours annually, the power cost is s cems per KWh (IHP 0.746W), the MARR is 10%. a)What s the Capital nacovary ceat for ths motor? Question 2 O out of 30 po nts what the total an mai electric ty cost tor this motor? 05 pts Question 3 O out of 20 po nts what is the total anual equivalent cost for this motor?

Explanation / Answer

present Salvage value=salvage value/(1+i)n
=250/(1+10%)^10=$96.39

Total horse power hours=2000
Net cost=4500=96.39=4403.61

Recovery ratio=(1+i)^n/[(1+i)^n-1]
=16.27%

a)Annual recovery cost= 16.27%*4403.61=716.67

Recovery per HP hour=716.67/2000=0.36

2)Total annual electricity cost=2000*150*0.746*0.05*83%=9287.7

3)total cost=300+9287.7=9587.7
4)cost per operating hour=9587.7/2000=4.8
