Maximum flow through pipe question
Maximum flow through pipe question
(OP)
Is there a calculation available to determine the maximum flow through 3/4" copper (type k) tubing? For example, if 60' of 3/4" copper tubing is connected to an 6" watermain, with a flow of 900 USGPM in the watermain and a static pressure of 60 psi, what is the maximum flow rate through the copper tubing?

Anyway, your numbers are off most of the tabulated sources. If for instance, you were selecting a new pipe size that you wanted 31 gpm through and had more typical pressure drops and velocities, you'd be selecting something more along the size of a 1-1/2" pipe. A 3/4" line is more typicaly used for single digit flow rates.
But since your question was more theoretical (like you could actually stand to lose the full 60 psi in 60 feet), I had to go to some on-line calulators and keep iterating until the pressure drop was 60 psi.
The following is a link to the first one that came up on google.

You have to figure entrance loss, exit loss, head loss, and pipe loss. I calculated 28 gpm.
