Thank you for this demonstration. I was having a hard time understanding why radius of the pipe increasing would increase the flow rate and this visual cleared out up for me. Thanks again!
In case anyone doubted the the Radius^4 part of the Poiseuille's Law this is a beautifully simple experiment to confirm it. Some verbal explanation would make it even better though.
I was happy to have found that the second tube’s radius was twice as large, and that there are 16 tubes in the first set. I reasoned from this that the flow must depend on r^4. Shortly after watching, I made a quick google search and confirmed my hypothesis. :)
A lot of effort to show a basic or somewhat advanced physics concept. Quite important as there are many instances of fluids flowing through pipes and hence knowledge and understanding of the Hagen-Poiseuille Law is important.
The laminar flow rate of an incompressible fluid along a pipe is proportional to the fourth power of the pipe's radius. So no, 2 times diameter, to the power 4 is 16.
Not sure exactly why anyone would downvote this video. It is what it is.
UA-cam releases bots to dislike videos so that their algorithm would be balanced.
It was Allen's Mom; she thought he should wear a tie.

Glad it helped!
Excellent demonstration of a 4th power law!
Glad you liked it!

apparatus very nicely designed.
It is great. Please add voice explanation as well.
Thanks Sir. from India
Thankyou for giving us practical example and making this setup
Great introduction to the law

Great...( 0.1)^4 times 16 is equal to (0.2)^4
I like it
Only thing missing is to see the numbers of the actual flow rate and corresponding math.
Verbal commentary/explanation would be a welcome addition to this video.
Sir Thankx (from India)
Why is it correlated with r^4?

4 times due to diameter, 4 times due to viscous force. Total 16 times. Am I right?

@@niemandwirklich thank you
Love this
Can someone help me by telling me the importance of poiseuille equation in real life? I read many articles. But i prefer a very meaningful concept.
It's important in medical contexts, such as blood flow through constricted veins.
PRESSURE - BALANCE
Cool thanks
Owesome
👍
*On its own power yes.. It will be different if you add some air pressure*
Yeah. It will be different if you do something differently...
Bigger pipe just has less friction
usefull
