This tool will calculate the estimated electrical cost to run an electric mine dewatering pump.  This is a great tool for calculating the cost needed to compare different pumping capacities vs duration for mine dewatering.

PUMPING COST  CALCULATOR		Example: A 200 HP pump motor operating at 95% efficiency and the electrical cost is $.09 /KWH. If the pump is run for 8 hours per day 5 days per week The electrical operating cost would be: $2,449.83 per month or $29,397.99 per year
