What can be the maximum size of the hole? The physical forces to be taken into consideration are: external pressure, internal pressure, surface tension of the fluid (ink=water). What is the formula?

$\begingroup$ You are right. It is a variable to implement in the formula. $\endgroup$– MrkLchCommented Jun 20, 2018 at 21:40
