Can anybody write me how to show the similarities in the Poiseuille law and the Newtonian viscousity force?

You've posted this in the homework forum, and therefore I will assume that this is homework. Note that, in these forums, you are required to show some work before we can help you.

So, you could start by writing down the definitions of the terms you introduce.
