Homework Statement
I don't know how to approach this problem, any help would be appreciated.
i have a pipe 1 meter in length and 4mm in diameter. it containts 2 gases, D2 and He-3.
each half of the pipe contains the 2gases and they are both at 400psi.
how long does it take the gases to diffuse across the pipe completely?
thanks.
Homework Equations
ive looked into grahms law of diffusion but that doesn't seem to be helpful at all in this situation since it give me a proportional rate b/w two different molecules of gas
The Attempt at a Solution
as far as I've gotten is finding the volumes of gas in each half of the pipe... not very far.
