First you need the size of the pipe and the volume of water supply. Pressure will vary during usage. Standard well system operates between 20-40 psi and city systems operate from 50-70 psi.

you need to know the viscosity of the liquid - molasses or alcohol?

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.

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.
What schedule piping as schedule 40 fittings are rated for 125# thus your 140 PSI would be really dangerous to try on standard fittings
You need to know the PSI (pounds per square inch) and GPM (gallons per minute). PSI * GPM = cleaning power.
It depends on flow. 2 PSI for 500 GPM 8 PSI for 1000 GPM 18 PSI for 1500 GPM 32 PSI for 2000 GPM This is per 100' ft If your flows are big, ie. defensive conditions, you must relay for anything over a couple hundred feet in length. Capt. Ridgeway Tumwater Fire
The time it takes to flow 300 gallons through a 1 inch pipe at 55 psi depends on the flow rate of the pipe. You would need to know the flow rate in gallons per minute (GPM) of the 1 inch pipe to calculate the time it takes. Without the flow rate, it is not possible to determine the exact time it will take.
