Well actually I was infering that for minimum thicness of the plate

explanation of two close spaced plates is a better description since
there are two entities there as with a water chamber separated by a
flexible gasket. Thus we have an application where a water analogy can
be used for energy transfer ie. Volume can change from one side to the
other by the deflection of the membrane yet the two entities still
stay separate. Neat.

Since water is for all practical purposes incompressible, you can't
change the volume of water that way, just the shape of the volume.

More psuedo-science babble.
