The average cost is 0 12 per kilowatt hour. For the monthly operating hours we will multiply the minutes per day of pump runtime times 30 days. Pump input power calculation formula or pump shaft power calculation formula. To calculate the power consumption of your water pump just put the wattage of your water pump operational hours and electricity tariff of your locality and you will get the units of electricity consumed by your water pump and the impact it has on your electricity bill.

This maxes out my 5500w generator at startup. Q flow rate in m 3 sec. The cost of electricity varies greatly by location in the united states. Pumpingenergy ep x 8760 equation 30 where.

The theoretical pump power can be calculated as. Pump input power p. The shaft power the power required transferred from the motor to the shaft of the pump depends on the efficiency of the pump and can be calculated as. Pump power calculator in imperial units si units.

E kwh day p w t h day 1000 w kw. I e efficiency of the pump is the ratio water horse power to break horse power. You will then multiply the three power consumption operating hours cost of electricity together to calculate total cost per month. You will have extra capacity left over for other items such as fridge or freezer microwave oven lights television etc.

The energy e in kilowatt hours kwh per day is equal to the power p in watts w times number of usage hours per day t divided by 1000 watts per kilowatt. C 0 746 q h c 3960 μp μm 1 where.
