Agreed.
No, the flux is not always zero at a point. Each level curve of $\Psi$ corresponds to a different value. It does make sense to talk about the flux at a point, once we have decided which level curve we are measuring the flux relative to.

Ok I think we are on the same page here.
I got an impression that author uses the word a stagnation point and a critical point interchangeably but they are not the same right? To me a critical point is a place where a function is not defined while a stagnation point seems to be a place where a vector field vanish. Am I right here?

Look up what a critical point is using the index at the back of the book. Your idea of a critical point is not correct. Vasco |
