Of all the thermodynamicists all over the world not one could think of a reason why the strange waterfall depicted in fig. 2 below should be discussed: http://energythic.com/view.php?node=208 "However we may try to go around this difficulty by not expecting the liquid to flow out at the edges, where the retarding forces are strong (sealing the edges), but through a hole drilled into the middle of the grounded plate, as shown in *fig. 2." Yet this is a violation of the second law of thermodynamics par excellence - water cannot but flow through the hole pushed by the high hydrostatic presssure between the plates: http://pages.csam.montclair.edu/~yec...damentals/Brev... Can. J . Phys., 60. 449 (1982), Fluids in electric and magnetic fields: Pressure variation and stability, I. BREVIK: "FIG. 1. Two charged condenser plates partly immersed in a dielectric liquid. (...) FIG. 2. The hydrostatic pressure variation from point 1 to point 5 in Fig. 1." http://farside.ph.utexas.edu/teachin...es/node44.html "However, in experiments in which a capacitor is submerged in a dielectric liquid the force per unit area exerted by one plate on another is observed to decrease... (...) This apparent paradox can be explained by taking into account the difference in liquid pressure in the field filled space between the plates and the field free region outside the capacitor."
