Hi PF!
Fluids in low gravity have a natural oscillation frequency ##\lambda = \sqrt{\sigma / (\rho L^3)}##, where ##\sigma## is surface tension, ##\rho## density, ##L## characteristic length.
Then given a particular object, say a sphere, is ##L=D## or ##L=r##? How about a channel; would ##L## be the length, width, or height, or what about, say, half-width? Any help is greatly appreciated!
