Mathematical Analysis of an Ideal ZED

No they don't.

MarkE, I believe I can calculate everything from State 2 to State3 with the information I have provided from here on (and with the dimensions shown in the diagrams):  http://www.overunity.com/14299/mathematical-analysis-of-an-ideal-zed/msg391999/#msg391999  If you can point out where something is missing I will make any necessary corrections or adjustments.  But continuing to demand that I provide something when you will not state specifically what is missing will get us nowhere. 

Now I did not show each step necessary to adjust the water levels from State 2 to State 3, but you have demonstrated the ability to do that in your calculations that correctly adjust from State 1 to State 2.  So I would not think that would be necessary.  Is it a demonstration of this step that you would like me to provide?

You're an engineer. You've been to university.  Then you know what you need to show:  For each value that you develop you need to show the equation that gets you there.  Express the problem into just one giant equation, or some number of simpler equations.  What you have shown are some values from some non-specific equations.  That's crap and you know it.

So either stop with the games and actually show your work, or call it a day.

ok   mondrasek, pencil,papper and calculator,
i guess my question have been answered. i will ask if i have more next time

i see marke asked you this, he said...

"If you want me to audit your work, then you need to show your work.  You can write out the equations you used, or you can enter them into something like Excel, or do whatever else you need to actually show the process you relied upon to get your errant results".

maybe, markE is waiting equations that you use, and only from you. 

add :
i dont know you have asked again before my post  markE , lol

That is exactly what I am doing.  Mondrasek is playing this BS game that it is up to others to second guess and then do the work he has supposedly already done in order to check his work.   Except that they won't be checking his work.  They will be checking their guess as to what his work might be.  It's stupid.

Well,, I am curious as to the the change in water level in the soda bottle,, and a little curious about the height of the little bottle in the vented, sealed and just released and the equilibrium reached after release.  Is that a change in the water height inside the little bottle without a change in the clearance from the top of the soda bottle to the, what is now, the top of the little bottle??

No tricks were played.  No water was added or removed from the system in between any of the pictures.  The photographs were annotated with text and arrows.  The collage cropped the photos to fit in a file that this server could take.  The photos were not retouched or Photoshopped in any way.  When the little bottle goes down the water in the outer bottle goes up.

So the water level in the soda bottle goes from Up to down a little down a little more and then up a little, and the little bottle is down the same then up and then the same,, but it looks like the water level in the little bottle went up in the last picture without the little bottle moving up.

You can tell where the little bottle is by looking at the clearance between the flexible part of the straws and the top of the 2 liter bottle.  In the fully down position the two straws closest to the camera align the bottom of their flexible sections to the top of the larger bottle.  In the next picture, both the water bottle and water within the water bottle have risen, while the water level outside has fallen as it must.  If the contrast isn't good enough I can retake the pictures using red food coloring in the water.

I keep wanting to rotate the pictures a little bit,, they are angled,, nit picking

Of course this little funny thing could be due to a change in camera position and angle, just making it *look* like there was a magical after the sealed event increase in water in the little bottle,, or maybe making it look like the little bottle did not raise anymore even tho it might have,, I mean it looks like the straws went up,, but then that also looks like the water level in the soda bottle went up as well,, and it looks like the bottle is both angled in the water as well as twisted,,

It looks like the camera was about 2deg CW.  That's not enough to screw with anything.  I use a simple tripod that has a swivel in it.  Apparently I did not get it dead level.

When in doubt:  replicate.  It is not difficult or expensive to do.

BUT, if I were to go with the photos as shown I would have to assume that the water volume in the soda bottle increased as well as the water volume in the little bottle as the little bottle was rising and the straws grew taller.

That would not be physically reasonable.  There is only one water volume and in the collage you can see the levels converge as air vents out the top of the smaller bottle.
