Fluid flow & mixture

[Taylor]

This doesn't have any real application anywhere; it's just something I thought of the other day. After posing the question to my Aerospace Engineering class, I don't have much more clarity.

Suppose there are two five-gallon buckets set next to each other. The first bucket is filled with Fluid A, the second bucket is filled with Fluid B. The two fluids are different, but they have identical densities. Bucket 1 has a hose in it, siphoning the fluid out onto the ground. A second hose goes from Bucket 2 into Bucket 1, running at the same rate as the first hose. Essentially, the level in Bucket 1 neither rises nor falls for the duration of the experiment.

After some amount of time, Bucket 2 will be empty, and Bucket 1 will be full of some mixture of Fluids A and B.

My question is this: At that time, what is the makeup of the solution? What percentage is Fluid A, what percentage is Fluid B?

If the experiment were performed again, would the results be repeatable? To what degree?
