Can any help me estimate the flow of water through a 1" and 2" line at 100psi - I am in a small city and they are telling me a 5/8" line does 30 g/m and a 1" will only do 60. As best I remember if you double the size, you mulitply the volume by 4, that being said, a 1" line should be about 80-90 Gpm. But I am definitely not a plumber.
Also is there a rule of thumb on the BTU/Hour on a 1" line with 8" of Water Column.
Thanks in advance. John

2" line with 40psi ==> 46GPM.

That is only the case if you have a large dead animal stuck in the line. You should get quite a bit more flow than that.
As an example check out this link: http://flexpvc.com/WaterFlowBasedOnPipeSize.shtml
A 2" line with little to no pressure drop should give at least 55gpm, with significant pressure drop and noise due to high velocity you can get as much as 200 gpm through a 2" line.
A 1" line will yield from 16 to 58 gpm depending on pressure drop.
You can find similar charts through a search for gas.

Well.... "2" w/ 40psi generats 46gpm" comes from the word from the guy from wascomat tech support.

why 46gpm, because washer connects to 3/4" hose, that's why.

You are changing your story again, and you will never get 40+ gpm through a 3/4" hose.
