The rules are pretty simple. First, the average of a perturbed or turbulent term is 0, because if it were not, then the average value would be incorrect. Second ...

They cannot be derived; they are conditions or requirements that we impose on the averaging operator. What we are striving for here is merely practical.

The Reynolds-averaged Navier–Stokes equations (RANS equations) are time-averaged [a] equations of motion for fluid flow.
