Pipe end and branch

Pipe end and branch

Pipe end and branch

(OP)
I have a pipe which is closed at one end and has a branch coming off it near the closed end.  Can I treat this as a simple 90degree bend or would the 'dead end' cause noticable resistance to the flow?

Would there be resistance coefficients for this case in ASHRAE Fundamental publications?

James.

RE: Pipe end and branch

The dead end will not cause any resistance and you may use this situation as bend

RE: Pipe end and branch

I would treat it as a flow through the branch of a tee.  It's going to have a higher head loss IMO than a the longer sweep you have in a elbow (if that is what moalarsa meant by a 'bend').

RE: Pipe end and branch

(OP)
Branch flow sounds the more likely solution as flow would almost pass the branch before going down it (as in branch flow).

Thank you both for your advice!

James
