How many GPM can a 3/4 copper pipe flow?
3-inch pipe: 1,900 gallons per minute….1/2″
| Assume Average Pressure. (20-100PSI) About 12f/s flow velocity | ||
|---|---|---|
| Sch 40 Pipe Size | ID (range) | GPM (with minimal pressure loss & noise) |
| 1/2″ | .50-.60″ | 14 gpm |
| 3/4″ | .75-.85″ | 23 gpm |
| 1″ | 1.00-1.03″ | 37 gpm |
How do you calculate gpm of a pipe?
For the best accuracy measure the flow 3 or 4 times and average the times together. The formula to find GPM is 60 divided by the seconds it takes to fill a one-gallon container (60 / seconds = GPM). Example: The one-gallon container fills in 5 seconds, breakdown: 60 divided by 5 equals 12 gallons per minute.

How many gallons is 8 pipe?
600 = 30,159.29 cubic inches. Hence the volume in US gallons is 30,159.29/231 = 130.56 gallons.
Subsequently, one may also ask, how many GPM can flow through a 2 pipe? Since the piping contains 1.63 gallons per 10 feet of pipe, multiply 1.63 by six and the final GPM is equal to 9.78 GPM of water flow from the 2-inch diameter pipe.
