There's no such thing as a fluid that cannot be compressed.
If I have misunderstood the claim made for this formula, I apologize.
What does this formula claim to do, and how does it work?
Well, you claimed that: "Some of the more well known folks here have come up the following formula for the momentum of an in-compressible fluid" so I figured I would immediately point out that this can't possibly be the case, since there's no such thing as an "in-compressible fluid".
Rushy's posts do not add anything to this discussion, and dodging the question and turning it back around on me is not helpful. I clearly apologized that I misunderstood and asked for clarification, to which Rushy replied with the above quote. Since Rushy is a moderator, I am not sure reporting him to the moderator is the right course of action, so I posted here as it states to do in the rules.
