Mathematical Analysis of an Ideal ZED

[mrwayne]

Only you nose gets longer each time you speak Wayne.  The "ideal ZED" does not get taller as it is compressed.  It gets taller as it relaxes, just like the compression spring it emulates.

Mark, I am sorry - I thought you were intentionally trying to confuse people - now I understand that you really did miss it.

Look inside the ZED for the Spring - not out side.

The taller happens inside.

    Yes mrwayne,
                I think if you were to compress a ZED laterally, it may well get taller.
     Hope this helps,
                      John.

    Webby,
            how much energy does your kitchen  tap need to stop the flow?

MarkE, I have never claimed that the internal energy increases except when we are adding that exact amount of energy as additional water Volume under Pressure.  This happens from State 1(x) to State 2.

You have shown, and I agree, that the internal energy decreases during the lift from State 2 to State 3.  I would like to see the calculation for the Work performed during that lift, since that Work is also energy that is leaving the system.

You had best reread your post #27.  Kindly show where in that post you mention external energy output.

I was hoping to have someone check my math and process of analyzing the 2-layer system before ever posting the 3-layer.  That has not happened and so here is the next model if anyone is interested.  It utilizes the exact same 2-layer model and adds an additional third riser on the outside.  That way the same calculations for the 2-layer portion to find the water levels after introducing the Vin volume "charge" could be re-used.

The PinVin I calculate now rises to ~2.103 mJ.  If PoutVout is to be equal to that per Boyle's law, then the system should stroke ~1.9094 mm.  That is drawn on the right hand side and analyzed to see if it is neutrally buoyant.  It is not, and actually is still pushing upward with ~31.8276 grams of force.  So the ZED would stroke further than shown until it could come to rest again with neutral buoyancy.  And that would require that PouVout would be greater than the PinVin of ~2.103 mJ.

Read your own words.  Inspect your own drawing.  The drawing depicts, and the text describes only internal energy.

I have shown all of my calculations, including after adding the 271mm diameter pizza pan of water.

LOL.  Wayne Travis, black box behavior is evaluated from the outside.  You lose again.
