Mathematical Analysis of an Ideal ZED

  Mond,
          OK. I give in.
         I was just following the Koala and his virtual water.

TK's highly descriptive phrase,"Virtual Water" needs to be copyrighted, IMHO!

    Surely something in a close fitting container can only displace a small amount of water.
     The weight can be balanced by "virtual water"  Trouble is when it comes to pumping
      there's no free ride.

Once we start talking about anything other than the Mathematical "Ideal" model, I agree completely.  There are obviously losses during all of the dynamic interactions in a Real World ZED Cycle.  Those loses would need to be incorporated properly into any complete simulation of a real world system.

So if an "Ideal ZED" system acts only as "Ideal" (IE efficiency of 100%), then real world losses would necessitate that it be less that 100% efficient.

BTW, this gives rise to one of my concerns about the claims that the "pre-charge" causes the dual ZED system to be able to cycle for the length of time as shown in Mark Dansie's video:  In my experience, the losses built into the entire dual ZED system would consume any excess Energy due to a "pre-charge" in only ONE or at best TWO cycles.  I contend that a precharged dual ZED system could not oscillate like a teeter-totter for several cycles, let alone the minutes shown in those videos.

My opinion is that something must be DRIVING the dual ZED system behavior that was video taped by Mark Dansie.  But that is only my opinion.

This is the cell for the air volume audit for Riser 2 with the VerGap set to 0mm and an error of

1156cir_mm2*mm

Riser 2 has a Risr2IDCirArea of

1156cir_mm2*mm

R2
=(Wall2Height_1-ST3_AR3_Height_1)*AR3CirArea_1+(Wall2Height_1-ST3_AR4_Height_1)*AR4CirArea_1+ST3_Uplift_1*(AR3CirArea_1+AR4CirArea_1+RingWall2CirArea_1)+Riser2IDCirArea_1

This is the cell for the air volume audit for Riser 3 with the VerGap set to 0mm and an error of

1764cirmm2*mm

Riser 3 has a Riser3IDCirArea of

1764cirmm2*mm

R3
=(Wall3Height_1-ST3_AR5_Height_1)*AR5CirArea_1+(Wall3Height_1-ST3_AR6_Height_1)*AR6CirArea_1+ST3_Uplift_1*(AR5CirArea_1+AR6CirArea_1+RingWall3CirArea_1)+Riser3IDCirArea_1


To me this means that the audit needs to be  +VerGAp_1*Riser2IDCirArea instead of +Riser2IDCirArea at the end.

To me this means that the audit needs to be  +VerGAp_1*Riser2IDCirArea instead of +Riser3IDCirArea at the end.

A vertical gap of zero means that the machine is a concentric set of sealed cans.  It is meaningless.

  mrwayne said "The ZED has more buoyancy than its total displacement".
  Does this statement mean anything?
  Under certain circumstances I don't think Archimedes would be too bothered
  about this.
      Seems to me this is what happens in the fish tank video.
