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?

I can confirm that falling droplets do have a final volume, just like falling bodies have a final velocity. This is due to the forces of gravity and air resistance acting on the droplet as it falls. However, the final volume of a falling droplet is not a fixed value and can vary depending on various factors such as the size and shape of the droplet, the viscosity of the liquid, and the height from which it is falling.

To determine the final volume of a specific droplet falling from a specific height, we would need to consider the properties of the liquid, such as its density and surface tension, as well as the air resistance it experiences during its fall. This can be calculated using mathematical equations and simulations, but it may also require experimental data to accurately determine the final volume.

In the case of a semen droplet falling from a 1km height, the final volume would depend on the specific properties of the semen, such as its density and viscosity, as well as the air resistance it experiences during its fall. Without knowing these specific values, it is difficult to accurately determine the final volume. However, it is possible to estimate the final volume using theoretical calculations and simulations, but this would require more information about the droplet and its surroundings.
