Thank you for the reply. Let's assume I know nothing about the water or gas content in the water (because I don't). Perhaps a simplified version of this problem would be as follows. Let's say we have a large box with an open top filled with standard air (nitrogen, oxygen, etc). The bottom of the...
Trying to determine diffusion rate of a gas emitted from a body of water. I believe Fick's first law may apply:
J = -D * (dc/dx)
where:
J = diffusion rate [mg/s×cm2]
D = diffusivity constant (can be looked up based on type of gas and local air temperature)
dc = change in concentration from...
