Pipe Flow Calculations Forum

I am working on district cooling by using chillers. how to size the chilled water header as the header accumulate flow of 5 chillers each is 9000 gpm. So total 45000 gpm. How to size the header.
Similarly the condenser water flow rate is 18000 each, so flow of 5 is 90000. How to size the pipe header.

You can use flow rate and diameter calculator at:

where if you enter water velocity of 2 m/s and density of 1000 kg/m3 you can get pipe diameter.
