Go away and don’t post your stupidity to me any more.
I’m not going to argue with a child who behaves like a liberal simpleton.
You’re debating an engineering question — an issue which can be resolved by facts and mathematical modeling. There’s no reason to resort to personal attacks. Political leanings (assumed or actual) have nothing to do with it.
In the particular case mentioned by Elsie, in her just previous post, Elsie is correct. The site she linked to provides a “Hydropower Equation” (click on the link, within the site). If you plug in the head, the flow rate, and an efficiency factor (0.5 is a good estimate); you’ll be able to calculate the output of any hydro electric setup (setting aside a lot of possible complexities that arise in some of the larger setups). Ten ft. of head, and 1,000 gpm through a turbine/generator with a 0.5 efficiency does indeed yield 1 kW output.
