Mathematical Analysis of an Ideal ZED

Of course he has. He has another meeting.

How did your meeting go? Pretty short meeting. Did you cut it short to rush back here and insult me, yet again?

The interview went well.

Now that I am sure you know the concept of making ignorant claims against other people is wrong - I will apologize to you when you do.

Wayne:

Without being specific to Larry because I haven't followed his spreadsheet, I note MarkE's comments:

And yet you endorse LarryC.   You endorse Webby when he can barely explain himself.   You are one piece of work.

With respect to you:
  - brainwashing attempt - brainwashing attempt - brainwashing attempt - brainwashing attempt

That one I can latch onto and agree with.

Wayne, please demonstrate YOURSELF that YOU have something.  That is the real due diligence.

Do you have anything?  ANYTHING?

I am sorry MH - you should ask Monderask or Larry to explain.

It is an eye opener - not a preconceived notion.

What would you do if I told you I was colorblind?

That would suck on so many levels.  But I think we could then resort to labels.  But it would be so much harder to follow.

My apologies to any colorblind individuals trying to follow along.

Just kidding. The outer part always sees the same pressure from the outside air, whether the yellow lines are out, in, or neutral. Therefore the outer air pressure doesn't make any difference between the three states. Open to the atmosphere is one thing, able to be affected by it is another. Your system is NOT open in the same way that the Cartesian Diver is, where the surrounding fluid pressure changes DO affect the buoyancy.

TK, I never said that the atmospheric air pressure makes any difference to any pressures inside the ZED.  Thankfully, it doesn't!  What having the outer annulus open to the atmosphere does do is allow for the V_in to NOT equal the V_out.  Because air also moves freely into and out of the system from the atmosphere and adds ANOTHER V (that is not costing us anything) that must be accounted for in an Energy Balance.

The air that freely crosses into and out of the system allows the water levels to redistribute to satisfy simple volumetric constraints.  And when allowed to do so it results in a lift force that is due to BUOYANCY, not the usual pressure * volume relationship found in a simple hydraulic cylinder.

Hello Monderask and Larry,

I had extra time between meetings, so I spent too much time here.

I am sorry if I disrupted the conversation.

Great work on the Math!
