comment Is the EmDrive, or “Relativity Drive” possible?
I'm guessing your explanation still holds given the new claims by the Chinese researchers right?

comment Is the EmDrive, or “Relativity Drive” possible?
I hadn't seen this question before and I [skeptics.stackexchange.com/questions/13543/… posted] something related to it on skeptics... Apparently there are some new claims from the Chinese researchers that this works. Has anybody read these papers? Do we know anything more about this?

comment Questions about compressing a liquid in a piston
When you say "If you push the piston further, the water will mostly just push back." that does indicate that of course my equilibrium pressure (i'm pushing very slowly) is increasing.I think my mistake was that in the case you do get a pure liquid in a given volume, the p-T conditions can be outside the boiling curve and thus there will be no evaporation right?

comment Questions about compressing a liquid in a piston
Well in my thought experiment, I cannot determine the temperature, but you are right, I probably should have called the fluid a compressed liquid (top-left quadrant of the p-T diagram) and not a supercritical fluid. Let me digest the rest...

comment What is the velocity area method for estimating the flow of water?
Your last edit about the incompressible fluid makes sense and I guess I misunderstood that you were still under that constant acceleration assumption. Sorry !

comment What is the velocity area method for estimating the flow of water?
This makes little sense. Why is the water decelerating if the pipe area decreases? We are still assuming a steady state regime right? I don't know if you are confusing compressiblity from an equation of state point of view or compressibility from a fluid mechanics point of view, but for what we were talking about, neither of them applies.

comment What is the velocity area method for estimating the flow of water?
Your last sentence is incorrect. If the area of the pipe varies and if we are still assuming an incompressible fluid (ie water to a good approximation), then velocity changes with area, not density.
