∙ 11y agoThe 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 86.03
Note: You also need to account for fittings in the loss calculations; while minimal several fitting will make a difference.

∙ 11y agoThe flow rate of water through a 0.75-inch PEX pipe at 40 psi would be approximately 17 gallons per minute (gpm).
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.
As many as could flow through before eroding the piping to the point of no more flowing through and it simply spewing about.
The maximum flow rate for a 1 inch diameter pipe is typically around 8-12 gallons per minute. To calculate the maximum volume, you would need to multiply the flow rate by the amount of time the water is flowing.
Approximately 142 gallons per minute will flow through a 4-inch pipe at 0 psi.
If the old steel pipe was half inch, it is recommended to replace it with half inch copper pipe to maintain consistent water flow. Using a larger diameter pipe (3/4 inch) may lead to reduced water pressure and inefficient operation. Stick to the half inch size for best results.

That depends entirely on the viscosity of the liquid in the pipe ! Water would flow faster than oil !
question cannot be answered because it depends on the water pressure
Water flow rate half inch PVC pipe 65 psi?
300 gallons per minute
2.5 gallons per minute

If the flow velocity remains the same the flow volume will increase by the square of the diameter ratio.(2/1.25) = 1.6 = diameter ratio1.62 = 2.56 more flow volume through 2 inch pipe compared to 1.25 inch pipe.
it would flow more easily through a narrow pipe
Depends on what's flowing (gas or water or something else) and under how much pressure.
Maximum PSI rating is on the outside rating of the pipe
Depends on what is flowing through the pipe and the temperature of the pipe.
