Sorry, my math was off.I have a 100' on my pump, and it only sucks about 2/3 gallon up. I think each 50' 1/4" hose will hold about 2/3 quart, and the piston takes about 2/3 quart, for a larger pump.
lol yeah I saw your original post about a 50' stretch of hose holding a half gallon of paint and was about to call you out on it haha! In my experience it's usually a bit shy of 1/4 gallon, filling up the siphon, prime tube and hose. Not a whole lot more for a 3/8" hose, just shy of 1/3 gallon.Sorry, my math was off.
The number of cubic inches in a 50' x 1/4" hose is...
3.14 X .125 X .125 X 12" X 50' = 29.43 cubic inches = .127 gallons
The number of cubic inches in a 50' x 3/8" hose is...
3.14 X .1875 X .1875 X 12" X 50' = 66.23 cubic inches = .286 gallons
I typically run 100 ft of hose. The minimum is 50 ft. I have ran 150-200 ft on some big gas sprayers. I typically use 1095 sprayers. For laquer or spraying door frames etc. I usually use a small sprayer.When spraying cabinet doors and boxes what length hose are you using? shortest 1 i can find is 25 ft. would be nice to have a shorter one instead of loading up all that paint in the longer hose. Or am i over thinking it?
