Which would have higher head: both being equal, 1/2" pipe or 3/4" pipe with a short 1/2" restriction? Thanks

    All is not equal

    The answer depends on both flow rate and total length.

    Depends

    on the length of the pipes vs. the length of the restriction -- but if the restriction is definitely short with regard to the length of the pipe, then the half inch will have greater head loss with flow.

    It's for an Air Compressor

    The air compressor has a 3/4" outlet, it's about 15' run to a retractable hose reel with 50' or 3/8" hose. So I guess the question is should I pipe it with 1/2" or 3/4". Thanks
