Or perhaps I am looking at this wrong.
I was not planning on using the elbow at all. I needed to get another nipple after the T, but all I had on-hand for my test was the 90. The venturi still worked. There was a noticeable difference with the air pump off, however the elbow would certainly present resistance to flow.
Sorry it looks misleading. I just needed something to pass the the blowpipe to make the venturi work.
