Help Needed with Pipe Sizing for Cooling Water System

Hi everyone,

I am working on a cooling water system and need some help with pipe sizing. The system has a pump with a flow rate of 500 GPM and I need to determine the best pipe size for optimal flow and minimal pressure drop. The system consists of several bends and elbows, so I am also concerned about the impact of fittings on the pressure loss.

What factors should I consider when selecting the pipe size. Are there any general guidelines or formulas to follow for calculating the pressure drop through the system. I do not appreciate any advice or resources you could recommend to make sure the system runs efficiently.
I also read this www.engineeringtoolbox.com/cooling-water-piping-systems-d_ blue-prism topic I could not find anything helpful.
Thanks in advance for your help.

Best regards,
