1" pipe would have a GPM flow of 55 GPM @ 40 PSI
Not including friction losses
That would depend on the pressure.
Yes, easily.
100
A pipe that is 10 inch would have the velocity of 2.75 feet. This is 2.75 feet with 722 GPM.
Under 400 GPM at best (without friction)
To find the maximum flow you would need to know the maximum pressure. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. The GPM would be between 300 GPM and 460 GPM through the nozzle. If it were simply a 3-inch pipe with an oversized pump, running at 100 psi with no nozzle, you could (in theory) move over 3,000 GPM through the pipe (ignoring friction loss). Even at 80 psi, a master stream through a 2-inch nozzle moves over 1,000 GPM.
It would 2.75 feet with a 10 inch pipe. It would be 2.75 feet with a volatility of 722 GPM.
80 gpm
you need to know the viscosity of the liquid - molasses or alcohol?
The standard formula to calculate flow(GPM - gallons per minute) from a CIRCULAR orifice is:29.7 * (the square root of the pressure) * (the square of the diameter of the flow orifice)EXAMPLE using 3/4" Pex Pipe(actual I.D. of 3/4 PEX Pipe is .677") and 40 PSI pressure:29.7 * 6.325(sq. root of 40) * .458(the square of the I.D. 3/4" pipe) =A GPM of 86.03Note: You also need to account for fittings in the loss calculations; while minimal several fitting will make a difference.
Before you can calculate the flow, you must also have the pipe size and its coefficient of friction.
Barely/Maybe. Exact values depend on the type of pipe, but at 2600 gpm your velocity in the pipe is pretty close to 30 ft/sec. That is at the very upper limit (really a little above) the recommended flow velocity in piping. Head loss would be about 15 psi/100ft. So, if you had a short length at this size and flow it might work OK, but for any significant length the head loss would kill you in pumping costs.
What schedule piping as schedule 40 fittings are rated for 125# thus your 140 PSI would be really dangerous to try on standard fittings
