dividing a water pipe to 2 branches

[Greg80]

Hello
I want to ask if I have a water pipe with flowrate 16 m3/hr.
This pipe will be divided to 2 branches.
I need for each branch to have 8 m3/hr.
The pressure drop in branch 2 is more than branch 1 , what can I do have the same flowrate at the 2 branches (8 m3/hr) ?
Can I put for example a globe valve at the beginning of each branch followed by a pressure indicator?
Please advice me with an economical solution

Thank you very muchh

branch 1 (less pressure drop than branch 2) 2"

branch 2 (more pressure loss than branch 1) 2"

I'd put the valves at the end of each branch and adjust the flow you want from each by varying their backpressure at any given time. You can also choose to flow the branches full, rather than have only partial flow along the bottom. (And exposed open ended pipes can allow insects and animals to crawl inside or to backfill with mud or other debris.)

You could use what we call a flow controller. Griswold Controls makes them

They allow you to set the flow rate you want to have in a line and they work by equalizing the pressure drop in the piping.

We use them for recirculating the hot water in a domestic hot water loop where the pressure drops in various loops are different.

I have not used one at your flow rates ~35 gpm, but the chart I use indicates they have some that go that high.

Check them out.
