I don't stop adding air, the air is still flowing into the tube at the same rate. I attached a picture of the system, The little blue pipe is constantly blowing air into the tube at the same velocity/pressure. You can see the barometer and the valve right next to it, The valve allows me to...

The tube which the air was sent through is approximately 25 cms long. One end is closed and is where the air constantly flows in, at a constant pressure, this is unknown. A valve allows me to control how much air is put into the 25 cm long tube. By covering the exit, I can build up pressure and...

I got that Re is Reynolds number, but I'm in high school, this is the first time I've heard of Re :/, also, I don't get how this will help me because the pressure isn't used anywhere, I'm using low pressures, 1.5 Bars, 2 Bars etc., so the change in density is negligible

Is the p for density, or pressure? Also, how can I multiply by 16/Re, where Re is not a number? Thank you though ^^ :)

For an experiment, I sent specific pressures of air strams through a tube and I was wondering if there was a way to calculate the speed of the air since I know the pressure and the radius of the tube where it left from.

Yeah that's right, but I found a way to do it so it's all good now :)

Homework Statement I need to do an experiment to verify the gas constant R and I can only use a lighter. The equation useful is PV=nRT but I don't know how I can find the pressure inside the lighter. Any help is appreciated! :D Homework Equations I don't know what other equation might be...

Oh ok, thanks for that! Now I can proceed :D

That's good to know, but I'm using air and not water :/

Hey everyone, this is my first post here, I hope this is a good place to put it. I take HL physics for my IB program and thinking of doing the EE on physics. I looked into Bernoulli's principle and thought this would be interesting. A good experiment is having a ping pong ball hover over a...
