hydraulic and cost engineers of a water-related project proposal of ABC Construction is trying to agree on which two different sizes of pipe for a new water main. A 300- mm line will have an initial cost of Php1,250,000, whereas a 450-mm line will cost Php1,750,000. Since there is more head loss through the 300-mm pipe, the pumping cost is expected to be Php 3000 more per year than for the 300-mm line. If the lines are expected to last for 30 years,which size should be selected on the basis of a A. present worth analysis B. future worth analysis using an interest rate of 10% per year?
