[QUOTE="Y Fan Wen, post: 7218339, member: 741"] It's all to do with the ratio. 2cuft/sec over 10 feet would be the same. So, big river, less drop. Small river big drop. In my own case 1 cuft and 200 feet actually gives 12kw. That's because it isn't actually 20 feet, I think it is 16 or 17 so I get an extra 2kw over 200'. If I was redoing my site from new I would probably go for about 20kw as the river flow is actually a bit more than our estimate 40 years ago. The present 8 inch pipe limits the output to 15kw so if the present genny dies (13kw) I would replace it with a 17kw one. The extra kw is so it wouldn't be running at 100% when flat out. I would have to use a 10 inch pipe for 20kw. [/QUOTE]
