Final volume of a falling droplet

eng442

First of all, do falling droplets have a final volume like falling bodies have a final velocity - in air?

If so, is there a way to determine such volume for a specific liquid and a specific height? More specifically, the final volume of a semen droplet falling from a 1km height.

hi eng442! welcome to pf!

water is, for all practical purposes, incompressible

so (although the shape may change) the volume will be constant

Eh?

There will be some evaporation, but that depends on the details- temperature(s), relative humidity, etc..

Odd question....

I have never seen rain drops the size of breasts, even small breasts, though possibly the size of a nipple. So yes, if you could form a very large drop of water, say the size of your typical breast then after falling for a kilometer the large drop would break apart towards some maximum size. If on the other hand you had a cubic kilometer of water and could drop it a distance of one kilometer, all at once, I think you might have some very large drops?
