Pressure Equalization between equal size outlets

[Wolverine72]

I am working with water in PVC piping and cannot remember the rules regarding pressure equalization in equal sized outputs.
i.e a 6" pipe with 3 equal sized outputs (2&quot, the outputs are approximately 10' apart and the flow in the 6" pipe is 330 usgpm. Will each outlet carry 110 USGPM???

Can anybody clarify this or remind me of the applicable Physical Law.

Your velocity in the 6" header is just under 4 ft/sec so the pressure loss is insignificant.

The flow out of each of the 2" take-offs is set by the piping connected to each and the delivery pressure/elevation each goes to.

Now, if you have the 3, 2" outlets discharging to atmosphere each will flow very close to 1/3 of the totol flow rate. Likewise, if all three have identical piping and delivery conditions, each will flow close to 1/3 of the total.
