I'm so confused... I think I got the meaning of flux, it's a scalar that indicates the "quantity of a vector field (of field lines)" that crosses a surface of a given area. So no time relation implied right?
First: is flow and flux the same thing in English when talking about physics? (in Italian we just refer to it with the word "flusso")
Why I often read, about fluid flow (flux?) : it's the quantity that measures volume that crosses a surface per unit time?
Is this a misunderstanding? is this the definition of flow rate?
Is flow rate and flow the same thing in the field of velocity of a fluid?
Is the mass ( or volume) of the fluid bond to the vectorial field in a fluid, or I can just pick the velocity of a point in the fluid without considering the mass?
Is flow rate the dual of current for an electromagnetic field?
How is current related to flux?
Maybe the key is the divergence theorem... I need some sleep +.+
It's a lot of questions but they are strictly related to each other, I guess, the point is that I studied those things separately, I can't build an organic connection in my head.
