How much does the cylindernow weigh?You are considering purchasing a compact washing machine, and you have the following information: • The Energy Guide claims an estimated yearly electricity use of 350 kW-hrs, based on 8 loads of laundry being washed per week. • The Energy Guide claims an estimated yearly operating cost of $38. This estimate is based on $0.1065 per kW-hr, and eight loads of laundry being washed per week. • Local electricity costs $0.086 per kW-hr. • You wash four loads of laundry per week. Based on this information, first calculate the energy that would be used by this compact washing machine in a year.

As part of the refining process, a certain heat exchanger (operated at high temperatures and with abrasive material flowing through it) must be replaced every year. The replacement and downtime cost in the first year is $165,000. This cost is expected to increase due to inflation at a rate of 9% per year for five years (i.e. until the EOY 6), at which time this particular heat exchanger will no longer be needed. If the company's cost of capital is 18% per year, how much could you afford to spend for a higher quality heat exchanger so that these annual replacement and downtime costs could be eliminated? Click the icon to view the interest and annuity table for discrete compounding when i = 9 % per year. Click the icon to view the interest and annuity table for discrete compounding when i = 18% per year. You could afford to spend $ thousands for a higher quality heat exchanger.
