Main Question or Discussion Point

Hello Forum
How much falling water would I need to potentially generate 3 KWatts (240 ACV @ 13 A) of electrical energy?

Assume we have 100% efficient electrical turbine generator.

Our location is residential so the height drop is restricted to say 5 meters max, the lower the better.


TIA

The change in potential energy in a 5 m height is mgh= m(9.81)(5)= 49.05m joules. How many Joules are there in 3 kw?
