It depends upon the velocity of flow and thus how much dynamic pressure you have. The length and type of pipe/hose will also contribute to the amount of friction, further reducing the velocity, pressure and available flow at the outlet.
Inch is a measurement of length, gallon is a measure of volume. The two can not be converted. There are 231 cubic inches to one gallon of water. W.r.litchfieldIf you're looking for the length of a...
Assuming you're talking inner diameter (ID) of the pipe some basic math will answer this question.
Volume of a cylinder = pi * radius^2 * length
So for us, pi *.25*.25*12 = 2.35619449 cubic inches...
The volume of a cylinder is [ (pi) x (radius)2 x (length) ].V = (pi) x (0.25 inch)2 (360 inches) = 70.686 cubic inches = 0.306 gallonThat's the volume of the pipe. We have no way to know how much...
