I am coming off a 1 inch meter that is coming from a 6 inch water main and looking to find out how many gallons of water will flow per minute if the PSI of the water in the 1 in line is 40. I have a machine that requires 15gals per minute but would like to use the existing 1 inch meter on the land if possible.

Thanks

What's the length of this 1" pipe (between the meter and your machine) ?
