comment finding equation of a water droplet
@Hossein I don't have really good suggestions actually. I was thinking about using dye, but that would not help you here. Suspended particle can be an alternative, but you also don't want to influence the liquid properties. Good luck anyhow!

comment finding equation of a water droplet
@Hossein Nice update. I don't see anything contained in these images already that could help. I am not experienced with experiments, but aiming lasers at droplets sounds really complicated, maybe it is better to try simple illumination first, and try to select based on some shadowing somehow.

comment finding equation of a water droplet
@Hossein Would it be possible to add a sample picture of both camera's? As I understand now, you are only looking at the boundary of the droplet, by which you automatically disregard a lot of information. As per the answer, you need to distinguish between only a few options, but maybe you already have this information?

comment How do the flow equations relate to the actual situation?
@tpg2114 I agree with you, but I think this is more a difference in terminology, i.e., some people call the condition at x=0 initial condition as well (not me!)

comment How do the flow equations relate to the actual situation?
I have a small remark with respect to your post. You name the equation incompressible, but still want to solve for $\rho$. Later you mention four unknowns (instead of 5). This is a contradiction.
