How many gallons per minute will flow through a 1.5 inch pipe?

Metric PVC Pipe

Assume Average Pressure. (20-100PSI) About 12f/s flow velocity
1″ 1.00-1.03″ 37 gpm
1.25″ 1.25-1.36″ 62 gpm
1.5″ 1.50-1.60″ 81 gpm

How many gallons per minute can flow through a 12 inch pipe?

Maximum water flow capacities in steel pipes – pipe dimensions ranging 2 – 24 inches

Pipe Size (inch) Maximum Flow (gal/min) Velocity (ft/s)
10 3000 12.2
12 4700 13.4
14 6000 14.2
16 8000 14.5

How do you calculate gallons per minute in 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 GPM can a 1 inch pipe handle?

37 gpm

Assume Average Pressure. (20-100PSI) About 12f/s flow velocity
1/2″ .50-.60″ 14 gpm
3/4″ .75-.85″ 23 gpm
1″ 1.00-1.03″ 37 gpm
1.25″ 1.25-1.36″ 62 gpm

Does pipe size affect flow rate?

At any given flow rate, flow velocity is inversely proportional to the t cross sectional area of the pipe. Smaller pipes will lead to higher flow speeds; larger pipes, will lead to slower flow speeds.

How many gallons per minute can a 4 inch pipe handle?

3,400 gallons per minute
4-inch pipe: 3,400 gallons per minute.

How many GPM can a 1/2 pipe handle?
