Problem
A particular chemical process deposits scale on the inside of pipes. The scale cannot be removed, but increasing the pumping pressure can maintain the flow through the narrower diameter. The pipe costs $20 per foot to install, and it has no salvage value when it is removed. The pumping costs are $8 per foot of pipe initially, and they increase annually by $5 per year starting in year 2. What is the economic life of the pipe if the interest rate is 12%?
