    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    Thanks Jeff and everyone, I have a few more things I plan on trying and will keep you and the others updated. In the next few weeks I have plans on a test that will conclusively prove of disprove my main idea. What we have talked about here is just part of the main idea. I wish I could tell...

    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    Thank you very much. I will read the information on the venturi effect. My original idea for this, was when you put your finger over the end of a garden hose you are restricting the flow yes, but you are increasing the speed of the water. I was thinking it would be the same doing this with my...

    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    Hmmmmmmmm... Do you think that at all speeds this will be the case? Because (I don't know for sure yet) But the speeds can be very high, just guessing right now, but could be around 80 to 150 mph or higher. You are also saying that pulling the air or pushing the air are the same, well then...

    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    Definition: Reynolds number Re is a dimensionless number that gives a measure of the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions. Well I didn't come up with that, that's for sure! I...

    Here is a actual pic of the part

    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    Bob, yes its a venturi. But instead of pushing air thru I am pulling the air from the large end of the funnel (venturi) Is that what you are seeing in my drawing? Thats what I am trying to accomplish. I do want to increase speed, I did not conceder turbulence, thank you. I will have to...

    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    I really need to measure the wind speed? Instead of trying to see what is happening in the tube. (without all the crazy smoke idea) The air going around the part and through the middle should be traveling faster. Is there a change in speed?

    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    Here is two drawings. the first is without the part. straight tube, vacuum being pulled through the tube. The next drawing is with the part in the tube. same vacuum. I think that the speed of the air going through the tube will be faster and increased volume. Hope that helps explain my...

    Why Has My First Question Received No Input?

    its the 20th post below this one. thanks

    Why Has My First Question Received No Input?

    I posted a question about a funnel in a vacumme yesterday

    Why Has My First Question Received No Input?

    Just a little input... Not sure why my very first question has not received any input? I was hoping on a little insight. Maybe the question is just absurd, and no one wanted to waist their time. Or no one could understand it? Who knows... Amateurs anyway! (thats me)

    Can a Funnel Create Faster Airflow in a Vacuum Experiment?

    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...
