What units are flux “flow” expressed in 2 D vector calculus?












0














I hope simple questions are allowed on stackexchange. As I am working examples of flux problem I see it is calculated the same as a line integral.



I am OK with direction since you have to pick one as a function of the direction of the vector field otherwise you wouldn't get anywhere and of course a flux is a line integral where the direction points orthogonal to the standard vector line integral calculation.



But , I must be missing something.



When I integrate a line integral I get work. Work is joules but what is flux?

    The flux is not a line integral, but the integral over a surface. The units are whatever vector the flux of which you are calculating times surface. E.g. the flux of a fluid's velocity is volume per time.
