Is there an equation that shows loss of flow with every bend/elbow
The subject like pretty much says it all.....wondering if there is a accurate way to estimate loss of floss in the pipes with each addition of an elbow etc...
thanks!

Using 3/4 for main pipes and 1/2 for all final connections.
Mostly working with PEX...

LOL I was thinking copper..
Pex nothing you can do to the pipe but increase size..
Im on a well and ran 1" trunk lines.. ( I would do the same with pex.)
Then run 3/4 to the fixtures... Then stub up in 1/2" to the fixtures..

Still need to know what it is your suggesting doing.
A 3/4 line will have about double the flow of a 1/2 line.
I could see using a 1' as a main from the street but unless you trying to plumb an apartment building I see no use for 1" main runs.

Increasing my lines to 1" mains did away with my issues..
Kind of like gas pipe you need more volume sometimes. How do you get more volume? Increase the pipe size...

Also Joe that link to pex is a novel. If you are trying to point out a section to prove a point then you should specify..
Its like me saying you cant use 2 traps under a sink and posting a link to the 300 page plumbing code book with no reference...
Make sense?

There is a section on flow loss - will red that later
