Hi, I am new here and have a love for Physics, a passion for it you might say. I have a premise that I believe it to be true. (we will see!) I am no Physicist by any means, so the only way to describe my problem is in real basic terms so here goes...
Lets say I have a clear tube that is 3 inch's inside diameter and three feet long. Inside this tube I have placed a funnel suspended in the middle, with the large diameter of 2 1/2 inches down to a small diameter of only 1/2 inch. I then pull a vacuum of let's say 10 inches on the end of the tube with the large end of the funnel facing the vacuum source.
Now my thoughts: I believe that pulling this vacuum will cause the air being pulled threw the tube and around the funnel will cause a air foil, low pressure. That is the air going around the funnel will be slower than the air going through the center of the funnel... if any at all. If this is true then the over all air flow will be faster with the funnel in the tube then without the funnel in the tube.
Well there you go. I am trying to test it as we speak, I am trying to pull smoke threw the tube to see the effect it has on the funnel. Have you ever tried to make smoke before! Its not easy! I have filled my garage full of smoke though and caused the smoke alarms in my house to all go off. Well I look forward to any input you may have on this. please feel free to ask questions of my idea. Thanks Dave
