Does anyone have a link to the article that came out within the last couple years detailing the fluid flow of water within a vessel, with and without the drain running?
I don't remember if it was in WaterShapes, or one of the other trade publications.
I believe that it was a NASA study, or done by a NASA scientist... I can't remember exactly.
I am working with the building official in my local town trying to convince him that drains in pools are unnecessary, and he was very intrigued by the study when I told him about it. I think that they are almost there in allowing pools to be built without drains, just a bit more nudging and I think they'll go for it.
