To test a fire pump for 100 gallons per minute (GPM), first ensure the pump is connected to a suitable water supply and all valves are open. Use a flow meter or a calibrated flow testing device to measure the water output at the discharge point while the pump is operating. Start the pump and monitor the flow rate until it stabilizes at 100 GPM, ensuring that pressure gauges are also checked to confirm the pump is functioning within its designed parameters. Document the results for compliance and maintenance records.
The maximum gallons per minute (GPM) capacity of a sump pump typically ranges from 30 to 100 GPM, depending on the model and size of the pump.
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.
If 27 means 27' in diameter, sure, why not?
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 flow of 5 hp motor pump is around 90 GPM.
BHP = Flow(GPM) X TDH(FT) x SG /3960xEFFICIENCY(%)Example: BHP = (100 GPM) x (95 Ft) x (1.0) / 3960 x .6BHP = 4.0
To determine the gallons per minute (GPM) a 1 HP pump can deliver at a total dynamic head (TDH) of 12 feet, you would need to consult the pump curve provided by the manufacturer. The flow rate (GPM) will vary depending on the specific pump model and design.
The EPA limits gas station pumps to no more than 10 gpm. The average gas station pump is between 5 and 10 gpm.
usually you would want a pump that could circulate the amount of water you have every hour so you would need a pump for 13000 gph but that's a substantial amout so if you could even find a pump that pumps half of that an hour you should be alright

Fire sprinklers are rated by gpm per square foot, plus the temperature at which they are triggered, plus the diameter of the spray (angle of the cone), among other things.
