when weight of drop exceeds surface tension times orifice diameter, the dripping will start.
how long it will take for drop to drop depends on the viscosity.

>depends on the viscosity.
the viscosity of pitch is approximately 230 billion times that of water

230.000.000 Pa s
I have dealt with 100 k Pa s but extremely shear thinning.
silver conductive paste and nano suspensions for example.
pitch is just another level of thicc

The viscosity is also dependent on ambient temperature and pressure. Historically, this was an issue due to seasonal changes where the original experiment was done.

can't you just extrapolate from previous drops?
