Pumping and Material Cost Analysis
The cost analysis was performed in order to find the best qualifying material; in this case a pumping cost analysis and a material cost analysis were performed. As shown in Table 14, the head loss was calculated for different material in order to find the pumping energy required for the specified flow demand. Table 15 shows the cost of energy of all materials in addition to the extra annual cost of each material compare to ductile iron pipe, and the present worth of those costs considering a fifty-year life expectancy.
