So, i just started an elementar study on hidrodynamics and I'm stuck with something.
We have that the circulation in a closed path Γ is given by:
##C_Γ=\oint_Γ \vec v⋅\vec {dl}##
And that, in a irrotational flow, ##C_Γ = 0## for any given Γ.
But if we have an irrotational vortex wouldn't ##\oint_Γ \vec v⋅ \vec {dl} \neq 0## ?
This seems contradictory, and i really can't notice how to handle with this.
Sorry if this seems too basic, but I'm really just starting with this topic.
