I agree with JohnGP in that this paper looks useful, but it looks like the values it provides are for the pressure drop in the small branch line, not the main line.
Hello, I'm looking for pressure loss information for a tee with a smaller branch size.
It's a 3" Tee with a 1/2" branch. Most of the flow carries on through the tee while a portion goes through the 1/2" branch. Is there a K value or equivalent length or pressure drop calculation that can be...
