With no pressure (that being the P in PSI), it is next to impossible for any liquid, let alone gallons of liquid, to pass through piping at any length.
Is the 1" inside or outside diameter?
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.
6.23377 US gallons.
One cubic inch is equal to 0.004329004 gallons. (cubic inches) * 0.004329004 = gallons
Do you mean a fixed length of 5 inch pipe or are you asking to the amount of laminar flow through a 5 inch pipe? There is not enough info here to answer. Need length of pipe and what you are asking.

that's what she said
1200
300 gallons per minute
2.5 gallons per minute
0 gallons per minute will flow threw any pipe at 0 psi.
Depends on what is flowing through the pipe and the temperature of the pipe.
Flow = Pressure / surface S = PI * ( Diameter / 2 ) ^ 2 now you can do the math... I can't tell with gallons, inch and psi.
We need to know what pipe material will be used.
Depends on the piping material as Hazen Williams formula kicks in for friction losses
That's going to depend on the substance flowing and the pressure behind it. Beer -- more Molasses -- less etc.
