I have a need to know how fast gas bubbles will travel from a variable depth in a liquid to the surface. I realize there are a lot of variables here, liquid density, gas density, temp. etc... What I need is a general guideline for calculating the time with different gases through a homogenesis liquid. Any direction to a good article / study or equations is appreciated. Bottom line is probably stated as needing to know the rate of acceleration of a gas in a liquid to the surface, it will be important to be able to calculate the max velocity of the gas too. Example, if I had oxygen at 100 m under water and Helium 100 m under water at what rate will oxygen accelerate to the surface compared to Helium. Thanks!
