How do you calculate gpm based on PSI and pipe size?
- Step 1: Multiply the constant 29.84 times the coefficient of discharge (cd).
- Step 2: Square the measured diameter.
- Step 3: Multiply those two numbers: 26.856 x 6.5025 = 174.6.
- Step 4: Find the square root of 62 psi, which is 7.8740.
- Step 5: Multiply the final two numbers to solve for Q, the discharge in GPM.
How many GPM can a 1 inch pipe handle?
| 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 |
What is the maximum flow rate through a 4 inch pipe?
Water Flow Capacity in Steel Pipes (sch 40)

How many GPM can a 6 inch pipe have?
Water Flow (GPM/GPH) based on Pipe Size and Inside/Outside Diameters
| Assume Average Pressure (20-100PSI). About 12 f/s flow velocity | ||
|---|---|---|
| 4″ | 3.85 – 3.95″ | 28,800 |
| 5″ | 4.95″ – 5.05″ | 45,000 |
| 6″ | 5.85 – 5.95″ | 66,000 |
| 8″ | 7.96″ | 114,000 |
How do you calculate gpm of a 5 gallon bucket?
To determine GPM using a larger container take the container capacity in gallons, divided it by the number of seconds needed to fill container, then multiply times 60. The result is the GPM. Example: Using a 5 gallon container it takes 14 seconds to fill the container. 5 / 14 X 60 = 21.4 GPM.
How many gallons of water can a 2 inch pipe hold?
Subsequently, one may also ask, how much water can a 2 inch pipe flow? This means that the 2-inch diameter pipe that is 10 feet long has an internal volume of. 218 cubic feet. Calculate the amount of water that can be contained in the section of pipe at any given time. One cubic foot of water is equal to 7.48 gallons.
What is the flow rate of a 1 inch water pipe?
The flow rate can be measured in meters cubed per second (m3/s), or in liters per second (L/s). How much water can a 1 inch pipe pass? 1-inch pipe: 210 gallons per minute. 2-inch pipe: 850 gallons per minute. 3-inch pipe: 1,900 gallons per minute.
How many gallons per minute does a 3 inch water line drain?
1-inch pipe: 210 gallons per minute. 2-inch pipe: 850 gallons per minute. 3-inch pipe: 1,900 gallons per minute.
How do you find the GPM of a water pipe?
Multiply 7.48 gallons by . 218 cubic feet and the amount of water in the pipe is equal to 1.63 gallons. Find the GPM if the flow of water is one foot per second. Multiply the one-foot per second flow by 60 seconds per minute and the flow is now 60 feet per minute.
