- Figuring for pressure change due to an increase or decrease in pipe size
I am attaching a standard 5/8" garden hose with approximately 70psi pressure to a copper pipe that is capped on the opposite end with mist nozzles mounted periodically along its length. I want the pressure at each mister to be as similar as possible. The hose attaches at the base, a solid line goes 8 feet vertically and then the misters are mounted on a horizontal portion. For my copper lines I have 3/4" copper and 1/2" copper and I am wondering which I should use to have consistency after coming out of the 5/8" hose and into the misting system.
