One crucial pump moves highly corrosive liquids from specially lined tanks on intercoastal barges into storage and preliminary refining facilities dockside. Beacuse of the variable quality of the raw chemical and the igh pressures imposed on the pump chassis and impellers, a close log is maintained on the number of hours per year that the pump operates safety records and pump componenet deterioration are considered critical control points for this system. As currently planned, rebuild and M&O cost estimates are increased accordingly when cummulative operating time reaches the 6000-hour mark. Information:- First cost: $800,000- Rebuild Cost: $150,000 whenever 6000 cumulative hours are logged. Each rework will cost 20% more than the previous one. A maximum of three rebuilds are allowed.- M&O Costs: $25,000 for each year 1 through 4 $40,000 per year starting the year after the…
