I see, so it sounds like the density of the water/methanol/salt is significant. In that case you have to make the density a function of the additional variable so the density variation is generated.

When water is mixed with water/salt/methanol, what happens? If the salt goes one way and the methanol goes another way you will have a density difference and a flow will be generated. If the salt and...
