Water Flow Capacity in Steel Pipes (sch 40)
Pipe Size | Maximum Flow (gal/min) | Head Loss (ft/100 ft) |
---|---|---|
3" | 130 | 3.9 |
4" | 260 | 4.0 |
6" | 800 | 4.0 |
8" | 1,600 | 3.8 |
Likewise, how do you calculate gpm from PSI and pipe size?
Besides, how do you calculate gpm in a 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.
How many GPM is 60 psi?
For water conservation purposes, the Federal Energy Policy Act of 1992 requires that all lavatory (bathroom) faucets sold in the U.S. have a flow rate of no more than 2.2 GPM at a water pressure of 60 psi (pounds per square inch). According to the same law, showerheads may have a maximum flow rate of 2.5 GPM.
