Your videos are incredible, you are literally teaching the chapters of my book that I don't understand and making it to where I understand what I am reading. Thank you so much !
Hi and sorry for the late reply! The semester got a way from me. This is a shorthand re-arrangement of d/du (u^2) = 2u. It's certainly not mathematically perfect to just split and rearrange a derivative, but this is in essence what is happening.
Hi! Yes, that's right. Irrotational implies inviscid, because if flow had viscous effects and a boundary it would generate rotation. However, flow can be rotational and inviscid, especially in a scenario when flow comes in with rotation.

Glad they help!
thank u professor for all that efforts. This is the best explanation
Thanks and glad you enjoy!
Great presentation! It helped me a lot.
Glad it helped!
Sir, a question: At 8:22 in the mathy derivation of Bernoulli, why can we say u du = 1/2 d(u^2) ?

Sir, can we say that irrotational implies inviscid but the converse isn't true always?

Brilliant
Thanks!
