Holes in spiral duct for air distribution
(OP)
I have a client who is insisting on using spiral pipe with holes for specific air distribution over certain areas. It has been a long time since I've dealt with the calculations to be honest, and cant seem to find my reference material. Can anyone one point me in the right direction as to how to size holes, and the static pressure for the holes.?
