Mathematical Analysis of an Ideal ZED

New diagrams.

I wanted to put all of the dimensions in one place and it is easier for me to see the different pieces by using more colors.  So, here is the initial state drawing.  I would like to know whether we are stipulating that we got to this state, or that we are following some assembly procedure in order to get to this state.

An assembly procedure would be needed to get to this initial state I think.  It would likely involve vent ports for allowing air to move out (equalize pressure) while the risers and water were assembled.  Those vent ports would then be sealed and not used during the cycle.

OK that works.  For now I will just assume that we can get to the state in the picture.  One other question:  I assume that the pod does not seat.  I used mythical 1um spacers for that.  The idea is that any water pumped into AR1 will freely flow underneath the pod.  Does that work for you?

[mondrasek]

Yes, there would have to be that mythical spacer under the pod.  That condition does move this model further from a truly obtainable real world construction but was the only way I could conceive of to start with no water in the pod chamber and still allow for no motion when the water charge is being introduced.  But since the entire model is bound by engineering ideals, we can make that spacer infinitely small.  Assigning it a very small value as you suggest should not cause a noticeable difference I think.
