A friend is planning to utilize a local stream to create electric power. The source of the stream is a small pond. He plans to have a 5 inch pipe start at/near the bottom of the pond and this pipe will follow the stream approximately 1056 feet to a culvert where he wants to put the generator. The drop in elevation is about 40 feet. The pipe will obviously be closed and have no air. Towards the end, the pipe diameter will be reduced, and I know that the velocity will increase and I'll need to use bernoulli's equation but before we even get to that point I need to know how much pressure will be coming out at the end of that pipe and I haven't been able to find an appropriate equation or method of getting there.
