13.19 A waste-holding lagoon situated near the main plant receives sludge daily. When the lagoon is full, it is necessary to remove the sludge to a site located 8.2 kilometers from the main plant. Currently, when the lagoon is full, the sludge is removed by pump into a tank truck and hauled away. This process requires the use of a portable pump that initially cost $800 and has an 8-year life. The company pays a contract individual to operate the pump and over- see environmental and safety factors at a rate of $100 per day, but the truck and driver must be rented for $200 per day. The company has the option to install a pump and pipeline to the remote site. The pump would have an initial cost of $1600 and a life of 10 years and will cost $3 per day to operate. The company's MARR is 10% per year. (a) If the pipeline will cost $12 per meter to construct and will have a 10-year life, how many days per year must the lagoon require pumping to jus- tify construction of the pipeline?(b) If the company expects to pump the lagoon once per week every week of the year, how much money can it af- ford to spend now on the 10-year-life pipeline to just break even
