Consider a solid sphere (capable of withstanding full vacuum) of 3m diameter filled completely with water resting at sea level. It has a 10cm hole at the bottom with a cork on it. If you open the cork, what is the time taken for water to completely drain out.
What happens for higher diameter spheres?
(In reply to re: solution (maybe)
Viscosity explains the ketchup, but surface tension will not retain the contents. And we can assume a vortex concept so that equally volumes of air and water are exchanged, well, on average anyway?
