Thank you so much for your lectures. but can you please include your lecture 7(effusion) in this playlist? That knudsen flow is confusing me.

I'm planning to complete all the missing lectures of the first part of the book by December 2023. I'm also working on lectures on theoretical mechanics...

but can you tell me why did we integrate from 0 to π/2 to find pressure from the expression (1/2)nvcosθvf(v)sinθdθdv?
@vincentmeunier7873 Жыл бұрын
Yes, it is best understood from page number 95 where the solid angle is drawn. You see there that theta sweeps 0 to pi/2 for a solid angle of "theta" opening

Why does the momentum transfer equal 2mvcos@??? I dont understand where did 2 come ?
@vincentmeunier78732 жыл бұрын
It is the change in momentum. It is initially -mv \cos \theta and then mv \cos \theta after the molecule hits the wall. Thus, the change in momentum is thus 2 mv \cos \theta
