Parallel piping system
Parallel piping system
(OP)
Hi,
I am currently designing a system where I have cooling water at 30 GPM that is pumped to a manifold with 4 outlets. Currently, the 4 outlets have a similar piping line, so the flow is equally split between the 4 lines. I want to add a wye union to one of the lines, but now the problem is that I have no way of controlling the flow rates in each line? I guess I would have to install control valves to adjust the flow in each line? Is there any other way that would be more simple?
Thank you.

This pump program seems pretty useful but I can't seem to download it. When I click on the link to download, I then have to enter my information but there is no button to click to download. Maybe it is because I am in Windows 7 ... Does it work for you?
Thanks for the advice,
Gabriel

If you want them to be the same, put a pressure regulator on each of the four (soon to be five) lines to provide a constant pressure to the service. That way if one line has a higher instantaneous demand, the regulator will give it more water while the demand is high. Orifices and manually throttled globe valves rarely work very well in real life because demand changes too much and too frequently.

If you added an additional outlet, you probably need to resize the original orifices, if you wanted to get equal flow.

Designing a distribution system involves many variables. The size, and length of the delivery line, manifold line and laterals, the orifice size and spacing, and change in elevation are all taken into consideration.
Once you know these variables, you can select a pump. The pump moves the fluid through the supply line and manifold to the orifices.
Spreading the water out evenly doesn't happen by accident or magic. A good water distribution system will typically have a pressure drop through the orifice of around 5 – 15 ft. of H20.

I have downloaded the file and I know of many others who have. try it on another system?
