Re: what is GPM flow rate through a 6" Schedule 80 at 75 PSI

Hi Michael, the admin answered the question that was posed to me. He was very helpful, and I thank him "For 10' 6" pipe with 75 psi on the start and flowing out to 15 psi (atm. pressure) you have very high flow of 7000 gpm and velocity of 24 m/s or 81 ft/s If you put any obstacles in the f...

Re: what is GPM flow rate through a 6" Schedule 80 at 75 PSI

The application is a 6" line at 75 PSI which we insert an in-line valve with a throat diameter of 3" at the output of the water meter. The question posed is, will the 3" throat be able to provide the same (or close to) GPM rate. As for pressure drop, it would be variable, not knowing ...

Re: what is GPM flow rate through a 6" Schedule 80 at 75 PSI

Thank you for your reply. I don't know how to make the calculation. If you were to assume an open end line (atmospheric pressure) at 75 PSI, can you calculate the max rate of flow (GPM) for me? Also, what would the f/s velocity be at 75 PSI? I saw a chart showing over 5k GPM for a 5" pipe at 75...

what is GPM flow rate through a 6" Schedule 80 at 75 PSI

I have a 6" sch 80 water line with 75 PSI, what is the GPM flow rate?. I'm installing a valve with a 3" ID on this 6" line. Does the GPM and PSI increase? What will the net GPM flow rate be? Thank you for any help.
