SDs indicates 7.6-hp at the duty point. Test results indicate 8.1-hp at the duty point. Therefore di2erence = 0.5-hp • 0.5 hp x 760 watts/hp divided by 0.917 motor e2iciency = 414 watts/hr • A pump will need to run approximately 15 hrs/day each day to meet demand • Most utilities are charging $0.16-0.20 per kwh. I assume they get a discounted rate b/c of there usage so I would assume they pay around $0.12 per kwh. 414/1000 kw x 5,475hrs x $0.12 kwh ~ $270 per year $270 x 10 years = $2,700 2
