Inducia Capillaria II

Every elementary text book of physics contains a derivation of the height H at which a column of liquid rises (or falls) up (or down) a capillary tube of inner radius r. The conclusion is H=K/r where K depends on the surface tension, a formula on which this bevy of Lakatosian monsters feeds. This diagram demonstrates, on a plot of H against the inverse radius, to a series of caillary tubes standing vertically in mercuiry. Ultimately, the depression of level corresponding to this formula exceeds the length of the capillary beneath the mercury surface.

HINT:
This dragon, as was Inducia Capillaria I, is a Lakatosian Monster.
The standard methods of dealing with such monsters are with rather more credit going to the dragon-hunter who succeeds in monster adjustment
for any commercial purpose is forbidden.
