This is my first post so bear with me. I have available 7600 gallons of water per minute with the head pressure of 150 feet. The question is what size penstock should I use for the delivery of the water to the generator? And what size generator and type would one use to obtain its optimal performance? What are the final kilowatts produced? If that is too much information to ask for than I can settle on what size pipe would deliver 7600 gallons of water in 1 min. from a height of 150 feet. I do understand that putting a generator at the end of this pipe will create a restriction and reduction in volume that I'm not sure how to account for since I don't know what the generator type or resistance might be. Any help would be appreciated.
