I would like to know how to predict when a flow of liquid---dichloromethane, actually---freely flowing downward through a small hole (varying from around .05 to .001 cm) will exit as droplets instead of flowing in a steady stream. I have been bouncing around the Internet for a good while now and everything I find is either too specialized or grade-school level. I'm not interested in the flow of polymer solutions, just a plain old low-viscosity Newtonian fluid.

I've learned how to predict flow rate using Poiseuille's Law and drop size using Tate's Law. Now I need to know how to predict if the flow will be a steady stream or drops. Drops is what I want, actually.

I need something simple, not something complicated.

My own chemistry/mathematical/physical background:Simple quantum mechanics. Mathematics through simple differential equations. Vector calculus. E&M theory, i.e. applications and analysis of Maxwell's Equations. Thermodynamics and statistical thermodynamics.

So I can handle a certain amount of math.

Anybody here have any links? TIA.
