Hi Chad! Could you clarify what you meant when you said that the height for the tube example was the same @ 3:28? I am not seeing how the height of both A1V1 and A2V2 are the same. Thank you!
Hey! When he says the height he means that the center of the big tube is in line with the center of the thin tube. Sometimes you see problems where one tube is higher/lower than the other, and in that case the higher tube would have more PE due to the height. hope that makes sense!
I have the same question, I don't understand why the potential energy for region 2 is greater than region 1. Is it because the Y (height) relative to region 1 is higher?
Hey Chad, I have a question.. according to Poiseuille's law, If my radius is reduced my pressure should increase and here according to Bernouli's principle reducing the radius reduces the pressure .. so how these two principles cotradict
Hey Nilan! Are you confusing pressure with flow rate in Bernoulli's equation? Let me know the part of the video you are referring to as a smalller radius increases the pressure in the pipe at constant flow rate.
@@ChadsPrep No, there is another equation that isnt in this video, its Poiseuille's law (another equation for flow rate) where it says that the pressure and radius are inversely proportional, so which one should I consider?
Hi chad! I was wondering in regards to question 10 can you reason that pressure in region 1 is greater than the pressure in region 2 because water flows from high pressure to low pressure? thanks!
All things being equal fluids will flow from higher pressure to lower pressure. But Bernoulli's equation allows us to account for when potential and kinetic energy are not equal, and when this is the case fluids may not flow from high pressure to low pressure. What you might say instead is that fluids tend to flow from higher energy to lower energy. So don't just assume where the pressure is higher and lower based upon the direction of fluid flow in an example like that in #10. Hope this helps!
After 2 semesters of physics and 3 months of MCAT prep... I finally understand. You should be getting paid for this!
Happy Studying!
This is an extremely good way to explain this topic. Very nice!
I need to say, I'm studying for my physics final in first-semester college, and these videos have figuratively saved my life. Thank you so much, Chad!
Great to hear - hope all your study pays off big dividends, and I mean that LITERALLY!
Amazing breakdown of Bernoulli's equation... I didn't understand static and dynamic pressure until I saw this. Thank you
Awesome and glad it was helpful!

Exactly Cerise-Chanel...couldn't have said it better myself. Any chance teaching is in your future?🙂
Thank you so much! Very well explained. I wish I had these videos in first year.
Glad it was helpful, Arveen - thanks for your comment.
Hello, can someone explain why the height for section 2 of the tube is bigger than section 1 of the tube. this is at 11:33. thanks.
