Pipe Length
You are trying to identify a section of your river/stream that falls quickly over the shortest possible distance. There may be several places that are suitable on your river. You also want the turbine to be as near to your house as possible to save on cabling costs.
Measure the pipe length using a long tape or wheel, be accurate, as this information will be required to buy the pipe and it’s important to get it right. Our web power estimator will advise the pipe size required, normally 2 inch (50mm) or larger.
