9. A chemical processing plant runs 24 hours a day, 7 days a week. A piping system is proposed to pump the liquid through the turboencabulator at 1200 gpm, with a pressure drop of 6 psi. The cost of energy to run this system is $0.12/kWh. Annual maintenance costs for the system are 3% of the annual operating cost. The annual income expected from installation of this system is $17,500, while the initial cost is $60,000. The system is expected to last 15 years with no salvage value. What is the ROI
