Posted: Sat Dec 24, 2005 2:57 amHere's a few pictures of the bench i've been throwing together. Right now it's a rigged-up pitot setup, measuring velocity with some bent copper tubing. I plan on picking up an averaging pitot tube from Bruce in a couple of weeks. only 6 motors for now.
Right now i'm in the process of rewiring the motors and sealing up the joints. After that a leak test.
For the heck of it, I tapped my U-manometer into the inside and outside bend of the first 90degree bend in the system, right under the plenum. i'm actually getting somewhat of a flow reading. Anyone ever hear of using a simple 90deg bend as a flowmeter? Or is it only applicable to heavier weight flows (non compressible)?
I'll add some more info in the following days. Sorry if the pics are too large.
