An engineer must choose between two pumps for use in a water distribution system. Both pump A and pump B will deliver water at an adequate flow rate and pressure head. The data for the two pumps are given below: Item Initial Cost (BD) Operating Cost per year (BD) Lifetime (years) Salvage Value (BD) Pump A 200,000 30,000 12 10,000 Pump B 300,000 23,000 12 60,000 1. If the interest rate is charge at 7%: a) which pump are you going to choose? b) If the lifetime of pump B is changed to 16 years, and the analysis period is 48 years, which pump is better? (using table to solve the question) a. Payback period b. Profitability index C. Internal Rate of Return d. Break-even Analysis (if applicable) e. Depreciation schedules (use one method only) f. PW, AW, or FW Analysis (use one method only) An engineer must choose between two pumps for use in a water distribution system.
