bro pls explain what is really the pressure in Bernoulli indicating. if the liquid is getting into a smaller area, then how pressure decreases. it is increasing, right?. i also experimentally know that a low-pressure area is created. but how and what that is? .
The total pressure head is made up of elevation head, pressure head and velocity head. In a straight pipe, elevation head is constant. Therefore, If you decrease the diameter of the pipe, this forces the velocity head to increases, so the pressure head must decrease to conserve energy. I explain this in this old video from 5:30 onwards: ruclips.net/video/qDA2Y3X3rNY/видео.html
you videos are extremely clear as it relates to content, and a great help in understanding the principles. Please continue to upload
Thanks for the comment, I'm planning to upload more content but it takes quite a bit of time! Hopefully more in the new-year.
Useful lessons thnks
Thanks for the comment, glad it was helpful!
love from INDIA
Great videos ,many thanks. Do you have anything on branching pipelines, connecting multiple reservoirs etc? Willing to pay!
Thanks for the comment. I currently don’t have any material on this, but will consider it in the future.
