How much does a 50Hz pond pump use in 1 day?

The power consumption of a 50Hz pond pump depends on its wattage and the number of hours it runs per day. For example, a 50Hz pond pump with a wattage of 50W that runs for 8 hours per day will consume 0.4 kWh (kilowatt-hours) of electricity per day. To calculate the cost of running the pump, you can multiply the power consumption in kWh by the electricity rate in your area. For example, if the electricity rate is $0.10 per kWh, the cost of running a 50W pond pump for 8 hours per day would be $0.04 per day.
